Paper Abstract

Multimode polymer waveguide circuit fabrication techniques were used to produce several low-cost devices applicable to fiber optic sensor instruments. A 2x1 coupler with 3% reference tap was constructed with 250 and 500 #m diameter plastic fiber pigtails. This coupler had a 2 dB excess loss and could be used to replace the bulk-optic, 3 dB beamsplitter in a fiber optic instrumentation package. Further, a miniature fiber-tipped pressure sensor was produced using waveguide circuit-based photofabrication principles. This device could provide a disposable, catheter-tipped sensor for blood pressure monitoring.
