ODIS’ New Laser Is A Work Of Art

The VCSEL uses the firm’s POET technology which unites both electronic and optical elements onto a single chip.

OPEL Solar International says its U.S. affiliate company, OPEL Defence Integrated Systems ("ODIS") has demonstrated laser operation for the first time in a new integrated device as part of its Planar Optoelectronic Technology ("POET") process.

POET creates high-performance devices by fusing light and electronics together on a single chip. Specifically, POET is a semiconductor-manufacturing technology that enables the monolithic fabrication of integrated circuit (IC) chips containing both electronic and optical elements.



By offering components with dramatically lowered cost, together with increased speed, density, and reliability, POET could potentially allow ODIS to fundamentally alter the landscape for a broad range of applications, such as tablet computers and smartphones.

Based on a proprietary Group III-V materials structure, the pulsed VCSEL operates at 980nm with a 12μm diameter vertical cavity surface and an output power of 1.7mW. In tandem with ODIS' previously-announced integrated detector - an HFET device - the laser enables inter-circuit optical connections between electronic devices for on-chip applications.

"This has proven, for the first time, an end-to-end technology for on-chip integration of photonic circuits can manipulate light signals on the same semiconductor framework as electronic signals," noted Leon M. Pierhal, CEO of OPEL. "This technology has the potential to overcome the constraints of copper interconnects in silicon-based chips, and it further validates the years of development invested in ODIS, as reflected in the potential market applications for POET technology, as well as its overall importance to our stakeholders."

Pierhal continued, "Let us keep in mind that this is the baseline laser that will serve as the foundation device from which greater enhancements are projected and in the process of development."

ODIS has also proven a number of other optoelectronic devices, including HFETs, optical thyristors, oscillators, and super-radiant light emitting devices, all able to be monolithically fabricated via the POET process. These devices are currently being validated for scale-up by a third-party fabrication facility.

The POET platform is also the basis for other ODIS projects, under various governmental agency grants, to provide next-generation optoelectronic devices. These include optical code division multiple access devices for avionics systems, combined RF/optical phased arrays, optoelectronic directional couplers, and ultra-low-power RAM.
