Optical switching between bistable soliton states of the second kind is demonstrated numerically when the amplification of the input solitons is suitably adjusted. The numerical amplification study is supplemented by Anderson's [Phys. Rev. A 27, 3135 (1983)] variational approach, which sheds considerable light on the observed numerical behavior, although it is not able to predict switching.

Optical switching between bistable soliton states of the second kind is demonstrated numerically when two parallel, straight optical fibers are evanescently coupled. The numerical switching study is supplemented by a variational analysis which provides a preliminary guide to what ranges of input parameters should be chosen for the switching simulations.

Optical bistable switching and optical triode operation have been carried out using an optical directional coupler switch fabricated by Ti diffusion into LiNbO3at the 1.15 μm wavelength. The on/off ratio in conventional bistable switching was 10 dB and that in complementary bistable switching was 13 dB. Amplification gain in triode operation controlled by laser diode was 4.8 dB. Complementary operation was found to reduce feedback gain and to improve the on/off ratio in optical bistable switching.
