Compact equation for the waveguides used in this project: 2.44-1.13*(lambda-1.55)-0.04*(lambda-1.55)^2
The Mach Zender interferometers (MZIs) designed here have the following transfer function:
I_o/I_i=(1/2)*[1+cos(beta*delta_L)]
Parameter Variations:
We have designed MZIs with three different imbalance parameters (∆L). In additional we have investigated the use of an adiabatic coupler.
