Abstract
A demonstration of the capabilities of an active AlGaAs based 1 X 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 X 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.
