Ho Quang Quy, Vu Ngoc Sau, Nguyen Thi Thanh Tam, Nguyen Van Hoa


In this article the equations for two waves propagating in two fibers of nonlinear Kerr coupler for optical Mach-Zehnder interferometer are derived. Based on the resolution of those equations, the expressions describing relation between coherent length, input intensity of the wave, nonlinear coefficient of refractive index for 3dB Kerr coupler are introduced and discussed.
