Compact four-channel reconfigurable optical add-drop multiplexer using silicon photonic wire

摘要

We designed and fabricated a four-channel reconfigurable optical add-drop multiplexer based on silicon photonic wire waveguide, which is controlled through the thermo-optic effect. The effective footprint of the device is about 1000 X 500 (mu)m~(2). The minimum insertion loss including the transmission loss and coupling loss is about 10.7 dB. The tuning bandwidth is about 17 nm, the average tuning efficiency about 6.11 mWm and the tuning speed about 24.5 kHz.
