We actualized a silicon photonics (SiPh)-based coherent optical subassembly (COSA) with a compact and low-height package for the next-generation transceiver form factors. We integrated optical functions required for transmitting and receiving digital coherent optical signals into a single SiPh chip. The COSA is applicable to 100-Gbps dual-polarization quadrature phase shift keying and 200Gbps dual...
We propose a high-speed and power-efficient CMOS-inverter-based driver for a silicon photonics-based segmented Mach-Zehnder modulator (MZM). The proposed driver is equipped with area-efficient three-dimensional inductors, which are suitable for flip-chip assembly with a compact area and for inductive peaking to increase the data rate. We also employ a dual-drive push-pull configuration to drive the...
