Coherent ePIC Receiver for 64 GBaud QPSK in 0.25 μm Photonic BiCMOS Technology
2019
Journal of Lightwave Technology
In this paper, we present a monolithically integrated coherent receiver with on-chip grating couplers, 90°hybrid, photodiodes and transimpedance amplifiers. A transimpedance gain of 7.7 kΩ was achieved by the amplifiers. An opto-electrical 3 dB bandwidth of 34 GHz for in-phase and quadrature channel was measured. A real-time data transmission of 64 GBd-QPSK (128 Gb/s) for a single polarization was performed. Index Terms-Silicon photonics, electronic photonic integrated circuit, single chip coherent receiver, optical communications.
