A 45 nm CMOS-SOI Monolithic Photonics Platform With Bit-Statistics-Based Resonant Microring Thermal Tuning
Here, we present a bit-statistical tuner that decouples tracking of optical one and zero-levels to realize non-dc-balanced data transmission, an “eye-max”-locking controller, and self-heating cancellation without need for a high-speed sensing frontend.
Single-chip microprocessor that communicates directly using light
This demonstration could represent the beginning of an era of chip-scale electronic–photonic systems with the potential to transform computing system architectures, enabling more powerful computers, from network infrastructure to data centres and supercomputers.
Quantum-correlated photon pairs generated in a commercial 45 nm complementary metal-oxide semiconductor microelectronic chip

75% Efficient Wide Bandwidth Grating Couplers in a 45 nm Microelectronics CMOS Process
In this paper, we demonstrate a highly directional vertical grating coupler with > 70% chip-to-fiber coupling efficiency (CE) and a 78 nm 1- dB bandwidth fabricated in a 45 nm commercially available microelectronics SOI CMOS process.
A Monolithically-Integrated Chip-to-Chip Optical Link in Bulk CMOS
A silicon-photonic link is monolithically-integrated in a bulk CMOS process for the first time.
Energy-efficient active photonics in a zero-change, state-of-the-art CMOS process
Based on a novel, “spoked-ring” active microcavity, we demonstrate optical modulators in an unmodified 45nm SOI CMOS process at 5Gbps with <5fJ/bit energy consumption; and filters with record thermal tuning efficiency of 2µW/GHz.
