Paper Abstract

Polymeric optical waveguides are fabricated by using optical polymer benzocyclobutene BCB). The properties of BCB include good thermal stability and high optical transmission. Anisotropic etching of BCB has been characterized by reactive ion etching. The output mode distribution has been examined by CCD measurement system. Also, an optical coupler based on multimode interference (MMI) effect has been designed and fabricated. We show that such MMI couplers can offer superior properties such as low excess loss and good tolerance to the variation of wavelength. The measurement results are presented.
