Quantum arbitrary waveform generator

Kan Takase, Akito Kawasaki, Byung Kyu Jeong et al. · Science Advances · 2022

Controlling the temporal waveform of light is the key to a versatile light source in classical and quantum electronics. Although pulse shaping of classical light is mature and has been used in various fields, more advanced applications would be realized by a light source that generates arbitrary quantum light with arbitrary temporal waveforms. We call such a device a quantum arbitrary waveform generator (Q-AWG). The Q-AWG must be able to handle various quantum states of light, which are fragile. Thus, the Q-AWG requires a radically different methodology from classical pulse shaping. Here, we invent an architecture of Q-AWGs that can operate semi-deterministically at a repetition rate over gigahertz in principle. We demonstrate its core technology via generating highly nonclassical states with temporal waveforms that have never been realized before. This result would lead to powerful quantum technologies based on Q-AWGs such as practical optical quantum computing.

Harmonic arbitrary waveform generator

Brock Roberts · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023

High frequency arbitrary waveforms have applications in radar, communications, medical imaging, therapy, electronic warfare, and charged particle acceleration and control. State of the art arbitrary waveform generators are limited in the frequency they can operate by the speed of the Digital to Analog converters that directly create their arbitrary waveforms. The architecture of the Harmonic Arbitrary Waveform Generator allows the phase and amplitude of the high frequency content of waveforms to be controlled without taxing the Digital to Analog converters that control them. The Harmonic Arbitrary Waveform Generator converts a high frequency input, into a precision, adjustable, high frequency arbitrary waveform.

RF arbitrary waveform generator

David Moss · 2026

We report a photonic-based radio frequency (RF) arbitrary waveform generator (AWG) using a soliton crystal micro-comb source with a free spectral range (FSR) of 48.9 GHz. The comb source provides over 80 wavelengths, or channels, that we use to successfully achieve arbitrary waveform shapes including square waveforms with a tunable duty ratio ranging from 10% to 90%, sawtooth waveforms with a tunable slope ratio of 0.2 to 1, and a symmetric concave quadratic chirp waveform with an instantaneous frequency of sub GHz. We achieve good agreement between theory and experiment, validating the effectiveness of this approach towards realizing high-performance, broad bandwidth, nearly user-defined RF waveform generation.

A Test Arbitrary Waveform Generator

V. M. Piksaev, D. I. Zaichikov, D. V. Pyanzin · Instruments and Experimental Techniques · 2023

The results from the development of a three-channel arbitrary waveform generator with the function of a programmable power supply for setting up and debugging automatic control system boards for converter devices that require synchronization with the network are presented. The features of the device are the ability to simulate a three-phase distorted network to check and adjust the synchronization of control boards and the presence of galvanic isolation between three channels, which allows for using the generator as a power source for three-phase circuits. The generator provides the formation of output signals for each of the channels in the voltage range ±25 V with a maximum current of up to 2 A. The frequency range of alternating signals of the generator is 0.01–10 kHz. Currently, the generator is used at PAO Elektrovypryamitel to simulate dips, network distortions, and phase imbalances and to tune phase-locked loop systems and analog and digital filters.

We have built a computer-controlled high-speed arbitrary waveform generator which has a bandwidth of 50 MHz. High-speed arbitrary waveform generators have a wide variety of possible applications. We built our waveform generator in order to produce repetitive, synthesized ‘‘noise’’ which can have any kind of statistical properties we desire. We have found this device to be quite useful in studying nonlinear mode coupling effects which occur when a weak warm beam interacts with waves on a slow wave structure.

Arbitrary Waveform Generator Based on LabVIEW

Yueqin Li, Jinping Li · 2009

The conventional signal generators are often unable to produce the specific or complex signals. An arbitrary waveform generator has been designed with LabVIEW and virtual instrumentation technology. The generator not only can produce sine wave, triangle wave and other conventional waveform, but also can generate a variety of demanding modulated signals and M sequence signals. Even more, it can produce the special signals through fitting data, input formula and hand drawing by mouse. This virtual instrumentation achieves the aim that produces arbitrary waveform and meets the needing of specific experimental or complex condition.

A time-domain photonic arbitrary waveform generator

Jinxin Liao, He Wen, Xiaoping Zheng et al. · Optics Express · 2012

A time domain photonic arbitrary waveform generator (PAWG) scheme based on multi-wavelength optical differential quadrature phase shift keying modulation in combination with differential detection is proposed and experimentally demonstrated. The time domain method shows advantages of large time-bandwidth product, good flexibility, fast waveform refreshing rate, and high waveform quality over the frequency domain method. In contrast with other proposed time domain PAWGs or photonic digital-to-analog converters, our PAWG proposal shows a greater dynamic range and a larger noise margin due to its bipolar output, and possesses good scalabilities both in resolution and sampling rate. Assisted with the integration technology, this PAWG presents a good prospect for broad range practical applications in future.

We propose an optoelectronic arbitrary radar waveform generator. It permits to generate predefined electrical waveforms according to radar specifications by driving phase and amplitude distributions of optically carried microwave signals. The control of amplitudes and phases of each radar spectrum frequency component is optically achieved by spatial light modulators (SLM). We present and experimentally demonstrate two ways to achieve the kilohertz high resolution between the frequency components of a radar signal at 7.1 GHz central frequency.

High-Frequency High-Voltage Arbitrary Waveform Generator

Ma Zizhuo, Lu Fuchao, Zhengquan Zhang · 2024

This paper introduces a high-voltage arbitrary waveform generator and its modulation method. The generator consists of an LCC full-bridge resonant circuit and a bipolar solid-state Marx generator. LCC provides isolated DC sources for the Marx generator, and the output voltage can be controlled by adjusting the operating frequency. The Marx generator outputs arbitrary waveforms containing multiple voltage levels as a multi-level inverter. The modulation method is a comparator-based approach that can achieve the output of arbitrary waveforms with the lowest switching frequency. The design of such an AWG is demonstrated with the simulations in MATLAB-Simulink.

On-chip arbitrary waveform generator and differentiator

Jianji Dong, Shasha Liao · 2016

Optical arbitrary waveform generation (OAWG) plays a critical role in many applications, such as generating optical ultra-wide band (UWB) signal, optical pulse radar, all-optical temporal differentiator, and test of optical communication system. Although lots of OAWG schemes were reported using mature fiber grating techniques, one of the most promising solutions is prone to be the miniaturization and integration with photonic integrated circuits, such as using indium phosphide (InP) platform, silica on silicon, silicon nitride or silicon platform. In this talk, we review our recent progress on some OAWG schemes using silicon platform and their applications in photonic computing. First, we report an OAWG and high-order photonic differentiator based on a four-tap FIR silicon integrated circuit. By thermally controlling the amplitude and phase of each tap, we obtain several typical waveforms such as triangular waveform, sawtooth waveform, square waveform and Gaussian waveform, etc. Furthermore, we demonstrate first-, second- and third-order differentiation based on the optical pulse shaper, whose spectra were tailored to the transfer functions of temporal differentiators. Especially, our scheme can switch the differentiator patterns from first- to third-order freely on a fixed photonic chip, and this is unable in our previous works such as cascaded microrings or cascaded Mach-Zehnder interferometers (MZIs). Second, we demonstrate radio-frequency arbitrary waveform generation using temporal synthesis. We compare two schemes of cascaded microring resonators and finite impulse response. There functional photnic chip has only millmeter size, low power consumption, and high frequency response. Third, we will demonstrate an OAWG scheme based on superposition of differentiated waveforms. Compared to the first two schemes, this one shows a more compact size and a more flexible operation.
