Abstract
UV bleaching of side-chain polymer PMMA/DR1 has been characterized at different temperatures and different UV bands. Broadband mid-UV bleaching at elevated temperature has been found to be most efficient and has been used to fabricate polymeric directional couplers. A fabricated passive directional coupler has achieved 26 dB extinction ratio in the cross state. The simulated output power ratios of various interaction lengths agreed with the measurements of the fabricated devices.Keywords
