Abstract :
We report a precisely tuned and reconfigurable wide-band twenty-channel second-order dual filterbank, with tunable channel spacing and 20 GHz single-channel bandwidth, fabricated on a silicon-on-insulator (SOI) platform. The crosstalk between channels is <;35 dB, and the thermo-optic tuning efficiency is about 28 μW/GHz/ring. This filterbank is suitable for on-chip wavelength-division-multiplexing (WDM) applications, and has the largest-to-date reported number of channels built on an SOI platform.
