Development of a fiber optic interferometer demodulation/multiplexing system using an active 1 x 10 photonic polarization-preserving fiber coupler

摘要

An integrated phase modulator/signal multiplexer has been demonstrated that can be used to demodulate a fiber optic interferometer's output. The phase demodulator/optical switches are monolithically integrated with an active 1 $MUL 10 photonics polarization preserving coupler. This device was fabricated with rib waveguides and etched-facet turning mirrors. Active multiplexing and demultiplexing of a fiberoptic interferometer has also been demonstrated using the active photonics chip. The active photonics demodulation/multiplexing system offers the advantage of nearly lossless splitting and functionality in an extremely small package size.
