ODIS Inc. affiliate to present at SPIE conference

SHELTON, USA: OPEL Solar International Inc. announced that its wholly-owned US affiliate company, ODIS Inc. will present two papers on the Planar Optoelectronic Technology at the SPIE Optics and Photonics Conference to be held August 21-25 in San Diego, California.

SPIE is the international society for optics and photonics to advance light-based technologies. The society advances emerging technologies through interdisciplinary information exchange, continuing education, publications, patent precedent, and career and professional growth. Dr. Geoffrey Taylor, Chief Scientist at ODIS, and members of the ODIS Team will present a paper in two sessions of the conference.

"The SPIE Conference is one of the most premier Optics and Photonics Conferences in the world today," said Leon M. Pierhal, CEO of OPEL. "Dr. Taylor and his team have presented regularly at this conference, and this year is no exception. Two invitations were extended in recognition of continuing achievements of POET to make a significant mark in semiconductor technology."

The first session is 'Design of microdisk modulators and detectors for high-speed integrated WDM systems'. A new modulator structure for intensity or phase modulation is described. The modulator is an integrated component within a Planar OptoElectronic Technology (POET) circuit that enables the integration of complementary transistors for logic and control. Modulation is obtained through the control of charge density in a modulation doped quantum well which results in a blue shift of the fundamental absorption edge. A microdisk geometry is used to achieve a small footprint, resonance-enhanced operation, and low switching energy. The device is ideally suited for on- and off-chip WDM interconnections which maximize the bandwidth potential of optical waveguides.

The second session is 'Resonant optoelectronic thyristor switches as elements for optical switching fabrics'. Optical switching nodes are described that are suitable for high density optical switching fabrics. The basic element for the optical switch is an optoelectronic thyristor which has three properties considered essential for the switching fabric. First it is binary with on and off states. Second, it is a static storage element. Third, it may be written with optical and electrical inputs.

The thyristor is configured as a microdisk and two coupled thyristors constitute a 2x2 switch. Multiple wavelength fabrics may be considered with negligible crosstalk (-20dB) between channels. The routing pattern is written sequentially and optically prior to data transmission.

POET creates high-performance devices by fusing light and electronics together on a single chip. Specifically, POET is a III-V semiconductor technology that enables monolithic fabrication of 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 alter the landscape for a broad range of applications, such as for server farms, tablet computers and smartphones.
