Quadrature outputs from fiber interferometer with 4 × 4 coupler

Not Accessible

Your library or personal account may give you access

Abstract

A broad stripe waveguide of width W and length L acts as a self-imaging 4 × 4 directional coupler if L = NW2/λ, where N is the effective index. When the arms of a fiber-optic Mach–Zehnder interferometer are connected to two input ports of this coupler, the powers at the four output ports vary in phase quadrature.
