Design and analysis of a 6-stage tunable MZI PLC for BPSK generation

Using the direct time domain approach and thermo-optic properties of silica, we show that a single spectrally periodic filter can generate any 4-bit binary amplitude and phase code pattern. We design and analyze a tunable 6-stage lattice-form Mach-Zehnder interferometer using silica-on- silicon planar lightwave circuit technology for generating 40 GHz pulse trains with arbitrary binary amplitude and phase code profiles from a uniform 10 GHz input pulse train.
