OneChip Photonics Announces Foundry Relationship with Global Communication Semiconductors (GCS)

OTTAWA, March 13, 2013 – OneChip Photonics today announced that it is working with Global Communication Semiconductors (GCS), an ISO-certified premier pure-play compound semiconductor wafer foundry, whereby GCS is providing a complete range of Indium Phosphide (InP) wafer processing services to OneChip. OneChip uses these InP wafers to produce its Photonic Integrated Circuits (PICs) for the Data Center Interconnect (DCI) and Passive Optical Network (PON) markets.

OneChip’s unique, regrowth-free, Multi-Guide Vertical Integration (MGVI) platform eliminates the need for multiple epitaxial growth steps. This enables OneChip to decouple epitaxial growth and wafer processing, while outsourcing both functions to independent, pure-play commercial foundries. Under this fabless model, OneChip has been working with GCS to process its OneChip-designed 4-inch InP-based wafers. This leverages the infrastructure and expertise GCS has gained through serving high-volume radio frequency (RF) electronics markets.

GCS’s foundry services, based on its state-of-the-art Opto and Heterojunction Bipolar Transistor (HBT) processes in Indium Phosphide, are a perfect match to OneChip’s fabless model, which is built around its regrowth-free PIC platform. Further, GCS’s Opto and HBT and OneChip’s PIC technologies share the same process and provide a unique Opto-Electronic Integrated Circuit (OEIC) platform. This, for the first time, enables both electronic and photonic integration on one substrate, within the same commercially available fabrication process.

Valery Tolstikhin, Founder and CTO of OneChip Photonics, said, “GCS is the most advanced, pure-play foundry of its kind, which offers Indium Phosphide and high-volume RF electronics processing technologies. Working with GCS gives us the commercial, high-volume processing capability we need to meet the strict cost requirements of the DCI and PON markets.”

Brian Ann, CEO of GCS, said, “Our InP-based Opto and RFIC process technologies have great synergies with OneChip’s PIC technology. We believe OneChip is a company that can create a truly volume business for photonics in the DCI market, with the unique ability to combine PICs and electronics to create the first optoelectronic circuits in InP.”

OneChip’s regrowth-free, PIC-based InP technology has proven successful in the very cost-sensitive, high-volume PON market, as OneChip’s PIC-based PON transceivers and Bi-directional Optical Sub-Assemblies (BOSAs) already are being deployed by the world’s largest PON system providers.

Now, OneChip is extending this technology to the high-volume DCI market. This market requires 100Gbps+ solutions with higher interface density and longer reach than those within the reach of currently deployed systems in 0.85um and multi-mode fibers. The DCI market also requires lower cost and power consumption than the solutions offered by the traditional telecom component vendors.
