Abstract

The phase jumps in a linear coupler and a nonlinear coherent coupler are demonstrated analytically. The theoretical results show that slight changes in the ratio of input powers or a mismatch in the linear coupler slight changes in the input power in the nonlinear coupler can lead to a phase shift of π. This characteristic of the coupler may lead to electro-optical switching with an ultralow switching voltage or to all-optical switching with low switching power.
