Abstract: An optical delay generator comprises a first waveguide made from electro-optically active material resonantly coupled to a second non-electro-optically active waveguide. The first waveguide contains a chirped distributed Bragg reflector structure which reflects optical signals at a specific wavelength at a specific reflection point within the structure. An electric field applied to the first waveguide changes the refractive index of the electro-optically active material and thus shifts the reflection point. Optical signals reflecting from the reflection point are resonantly coupled into the second waveguide, and are thus not affected by the electric field applied to the first waveguide. The controllable optical delay applied to the optical signals results from control over the reflection point and the round-trip travel time for an optical signal forward propagating in the first waveguide, being reflected at the reflection point, and backward propagating in the second waveguide.

Abstract: A polarization controller comprises a plurality of devices connected in series to each other. Each device includes an optical channel waveguide which is common to the plurality of the devices, and an electrode positioned on the optical channel waveguide and two electrodes positioned on both sides of the optical channel waveguide. A retardation induced by electrooptic effect in each device is adjusted by voltages applied to the electrode and the two electrodes. The voltages are not kept increasing or decreasing, but changed periodically so that there is no limitation in an operating range for controlling a polarization of light which is propagated through the optical channel waveguide.

Abstract: This invention relates to an optical waveguide switch and directional coupler providing variable coupling between two optical fibers. The coupler is fabricated in semiconductive material such as GaAs or GaAlAs. A double heterostructure is used having a higher index of refraction middle layer. Optical fibers are inserted in channels in the semiconductive material. Varying the reverse bias across the heterostructure junctions located in the material between the channels electrically changes the refractive index of the material and alters the coupling between the fibers. The device is applicable to switching in optical communication systems.
