Integrated Compound Semiconductors Ltd (ICS) - a spin out from the University of Manchester that designs and manufactures RF, sensing and optical devices - has announced the availability of a new product line of high-speed InGaAs-InAlAs PIN and avalanche photodiode (APD) detectors.

The portfolio includes three-pad (G-S-G) and dual-pad variants for 10Gb/s and 25Gb/s datacom and telecom applications, developed on a 4” indium phosphide (InP) wafer process platform in partnership with the Compound Semiconductor Centre (CSC) - a joint venture founded in 2015 between Cardiff University and epiwafer foundry and substrate maker IQE plc of Cardiff, Wales, UK.

The 25G PIN platform offers proven performance of >22GHz (3dB) bandwidth, for a top-entry-illuminated design with a responsivity of 0.8A/W for a 20μm aperture in both single-element and quad (4x1) arrays. The 10G APD platform offers 7-9GHz (3dB) bandwidth, for a 30μm-aperture top-entry-illuminated design with a responsivity of > 0.8A/W and sensitivity of -27dBm with appropriately matched transimpedance amplifiers (TIAs). Currently, ICS is undertaking chip-scale sampling of discrete single-channel devices, and is planning to extend the portfolio to offer custom array variants for multi-channel 100G+ transceiver architectures throughout 2018.

“The rapid growth of the high-speed optical transceiver market is an exciting opportunity for the in-house skills at ICS as the demands of the 100G markets require a deep understanding of RF component design to complement high-quality optoelectronic device manufacture,” says ICS’ founder professor Mohamed Missous. “The relationship with CSC offers a rapid scale to volume through the connection with IQE,” he adds.

“ICS is one of our lead industrial engagements and it is pleasing to see the business model of the CSC working to deliver real tangible benefits to the supply chain for high-speed optical components for ultrafast fiber broadband communication systems,” comments CSC director Dr Wyn Meredith.
