Abstract: An optical transmitter (TX) data path is demonstrated in 28-nm CMOS which drives an 850-nm vertical-cavity surface-emitting laser (VCSEL) up to 56 Gb/s non-return-to-zero (NRZ). A dc-coupled single-ended voltage-mode driver employs area- and energy-efficient equalization… read more here.

Abstract: In this study, we propose an eight-channel monolithic optical transmitter using silicon electro-absorption modulators (EAMs) based on free-carrier injection by Schottky junctions. The transmitter consists of a 1 × 8 silicon arrayed-waveguide grating (AWG) and… read more here.
