Abstract :
We present a new single-stage AOTF with low insertion loss of 2.6 dB and low crosstalk between -20 dB and -40 dB at 100-GHz channel spacing. An unique parallelogram design which consists of straight optical waveguides and double-stage polarization beam splitters contributes to reducing both insertion loss and crosstalk
