Implementation of an active AlGaAs-based 1x10 photonic polarization preserving fiber coupler in a fiber optic sensor demodulation system

摘要

Abstract: A demonstration of the capabilities of an active AlGaAs based 1 $MUL 10 photonic coupler is presented along with an Optically Coherent Frequency-Domain Reflectometer (OCFDR) Fabry-Perot demodulation system. The increased capability of the active 1 $MUL 10 photonic coupler allows for the simultaneous multiplexing and demodulating of up to ten parallel Intrinsic Fabry-Perot Interferometric (IFPI) fiber optic sensors. A demonstration of the amplification and switching ability of the photonic device is also presented along with a comparison of the active photonic device with current polarization preserving fiber optic couplers. Future developments and improvements of photonic devices and their effect on future fiber optic sensors systems will also be discussed.!25
