Abstract
A wavelength-division multiplexed (WDM) polarization-independent transmissive modulator (PITM) that receives a multi-wavelength continuous wave (CW) light of indeterminate polarization, splits the multi-wavelength CW light into two transverse electric (TE) polarized components, demultiplexer the polarized components into single-wavelength CW lights, modulates the single-wavelength CW lights using four-port cross-state or bypass-state modulators, multiplexes the modulated output of the four-port modulators (FPM) into two polarized modulated components, and combines the two polarized modulated components into a multi-wavelength modulated output signal.
