Improved Power Budget of 112 Gb/s/$\lambda$ Intra-Datacentre Links Using a Split-Carrier Transmitter Architecture

IEEE Photonics Journal, 2019
A split-carrier transmitter is proposed to improve loss budget for short distance 100 G-per-wavelength intra-datacentre links. By applying a low-complexity hardware modification to the transmitter, the proposed architecture reduces transmitter ...

Polarization-Rotator-Free Polarization-Diversity 4 $\times$ 4 Si-Wire Optical Switch

IEEE Photonics Journal, 2016
We present a polarization-diversity 4 $\times$ 4 optical switch composed of silicon-wire waveguides. The proposed 4 $\times$ 4 switch does not require a polarization rotator, which enforces a modification in a standard complementary metal–oxide&#

An optical modulator based on a single strongly coupled quantum dot - cavity system in a p-i-n junction [PDF]

, 2009
We demonstrate an optical modulator based on a single quantum dot strongly coupled to a photonic crystal cavity. A vertical p-i-n junction is used to tune the quantum dot and thereby modulate the cavity transmission, with a measured instrument-limited ...

28 Gb/s direct modulation heterogeneously integrated C-band InP/SOI DFB laser [PDF]

, 2015
We demonstrate direct modulation of a heterogeneously integrated C-band DFB laser on SOI at 28 Gb/s with a 2 dB extinction ratio. This is the highest direct modulation bitrate so far reported for a membrane laser coupled to an SOI waveguide.

Optical interconnection

III-Vs Review, 2004
AbstractTransceivers based on the XFP Multi Source Agreement (MSA) are making high-speed optical interfaces so simple and cost effective that 10Gbit/s XFP products are becoming the de facto standard in optical access, metro, and long-haul transmission systems and are speeding the convergence of the telecom and datacom infrastructure.

VCSEL-Based Light Sources—Scalability Challenges for VCSEL-Based Multi-100- Gb/s Systems

IEEE Photonics Journal, 2012
Future high-performance computers require optical interconnects with aggregated Exa-Byte/s data transport. Densely packed arrays of vertical-cavity surface-emitting lasers (VCSELs) might present the only feasible technical solution.
