Abstract
PURPOSE:To make an optical switch very small in size and, at the same time, to operate the optical switch under low-voltage conditions, by using a gain guiding type waveguide which utilizes a gain difference caused by carrier injection into a semiconductor material as one of plural channel waveguides. CONSTITUTION:A buffer layer 4, activating layer 5, cladding layer 6, and gap layer 7 are piled up on an N-InP substrate 3 and P-diffused areas 9a and 9b are formed through an SiO2 mask 8. The electric current injecting part of the activating layer 5 acts as a channel waveguide and, when electric currents are injected into electrodes 11a and 11b, incident light 31a advances straight on and becomes outgoing light 31b. When the current injection into the electrode 11b on the opposite side of the incident side is stopped, a level difference in refractive index is produced at the central part of the intersecting section and the light 31a is totally reflected and becomes another outgoing light 31c. Therefore, when the current injection into the P-side electrode on one side is turned on/off, this optical switch makes switching operations and the voltage variation required for making the switching operations is about 2V. Accordingly, an optical switch which is very small in size and low in voltage can be obtained.
