Compact low loss single air interface bends in polymer waveguides

Year: 2004

Type: article

Abstract: We report the design, fabrication, and measurement of high efficiency, compact 45 degrees single air interface bends in low refractive index contrast waveguides in a low refractive index material system. Using standard microfabrication techniques, the bends are fabricated on silicon substrates using perfluorcyclobutyl (PFCB) copolymers, which feature a high glass transition temperature and low absorption loss. The measured 45 degrees bends have a loss of 0.30+/-0.03dB/bend for TM polarization and 0.33+/-0.03dB/bend for TE polarization.
