Low-Crosstalk Simultaneous 16-Channel × 25 Gb/s Operation of High-Density Silicon Photonics Optical Transceiver

We successfully developed a high-density broadband 16-channel × 25 Gb/s on-package silicon photonics optical transceiver. The flip chip bonded bridge structure realized high density of about 363 Gb/s/cm2. We demonstrated simultaneously on all 16 channels error-free operations with low crosstalk penalties of Tx-to-Tx 1.4 dB, Rx-to-Rx 1.4 dB, and Tx-to-Rx <;0.1 dB.
