“…Willinger peak powers of 7.3W , yielding a PSER of 10dB. A similar device was used in the pump-degenerate configuration [12] and achieved a higher PSER of 18dB with a 6W peak pulse pump power. A 40mm long silicon waveguide with a reversebiased PIN junction [13] reached PSER values between 10dB and 20dB with total peak pump powers of 0.25 − 0.63W .…”
