Low crosstalk simultaneous 12 ch × 25 Gb/s operation of high-density silicon photonics multichannel receiver

We developed high-density silicon-photonics multichannel receiver and demonstrated 12ch × 25 Gb/s error-free operations at the bit-error-rate of <; 1E-12 for the pseudo random binary sequence (PRBS) of 2
³¹
-1 signals. Carefully designed high power integrity successfully led to very small crosstalk penalty of 1.2 dB under the simultaneous operation at all 12 channels.
