H. Venghaus et Cm. Weinert, POLARIZATION-INDEPENDENT MACH-ZEHNDER INTERFEROMETER ON III-V SEMICONDUCTORS, IEEE photonics technology letters, 5(10), 1993, pp. 1213-1216
A new design concept for a rib waveguide-based polarization independen
t Mach-Zehnder Interferometer is presented, and a device in the GaInAs
P/InP material system is simulated combining a full vectorial two-dime
nsional finite difference calculation with a coupled mode formalism.
