Bandwidth and p ower consumption are two primary physical and practical obstacles in conventional me tal interconnect to keep Moore’s Law valid in complimentary metaloxide semiconductor (CMOS) circuits. Silicon (Si)-based photonics have been heavily studied to provide an highly integrated, low-cost and volume photonic interconnect solution. We review our effort to develop a new laser control mechanism and employee advanced III-V epitaxial materials in the promising heterogeneous laser platform.

Monolithic CMOS silicon photonics technology enables functional system on chip integration of complete electro-optic subsystems and single-chip transceivers. A complete set of building block components has been designed and integrated within a single manufacturing process that targets O-band data communication standards including direct-detect and 4×25 Gb/s WDM transceivers; however, the nanophotonic building blocks and diverse process features can be utilized for a wide variety of applications, including environmental trace gas sensing, medical diagnostics, and quantum interconnects. Automation, simulation and verification support for the optoelectronic elements in industry standard CAD tools enables small teams to reliably design complex systems.
InP PICs for Coherent Optical Transmission
Oclaro, Caswell, Towcester NN12 6RA, UK
The widespread deployment of digital coherent optics has been underpinned by the development of sophisticated optical components to provide functionality for transmit and local oscillator (LO) laser, dual-polarisation (DP) in-phase and quadrature (I&Q) modulator, and integrated coherent receiver (ICR). Working together with CMOS digital signal processing (DSP), digital optics has transformed long-haul optical transmission over the last few years, and is increasingly attractive for metro and data-centre applications.
