English abstract:
This paper presents an eight-channel optical transmitter and receiver circuit fabricated in 0.35 µm SiGe BiCMOS and integrated via inter-wafer connections to a photonic circuit fabricated in 220 nm SOI photonic technology in a 200 mm CMOS foundry. Measurement results demonstrate 8×1 Gb/s for transmitter and 8×10 Gb/s for the receiver. The transmitter´s extinction ratio is 5 dB. The receiver shows a sensitivity of -8.5 dBm at 10 Gb/s and a BER of 10-9, with a significant margin for improvement by optimizing the grating coupler efficiency, by a better fiber coupling, and to a lower extent by better matching the output impedance of the circuit.
