QPSK Transmitter Photonics Integrated Circuit (PIC) with Integrated Micro-Transfer-Printed EAMs and Custom Driver Compatible with 3D Integration

We present a 64 Gb/s O-band Quadrature Phase Shift Keying (QPSK) coherent transmitter, consisting of a silicon photonic transmitter (TX) integrated with micro-transfer printed (MTP) InP electro-absorption modulator (EAM) and a differential driver. We also show a co-designed flip-chip compatible electronic integrated circuit (EIC) and the photonic integrated circuit (PIC) based on the previous design.
