CESG Seminar: Optical Interconnects: Technology and Challenges

May 1, 2015 @ 3:55 pm - 5:00 pm

Room 1037 ETB

O. Eknoyan /Professor ECEN/TAMU

Abstract: Photonic applications are being demonstrated increasingly in diverse areas including medical analysis, flexible displays, wearable devices, and optical interconnects among others. This surge is a result of the evolving advances in the fabrication infrastructure of the semiconductor industry. The semiconductor technology, however, is primarily directed toward controlling the flow of electrons rather than photons. Seizing the full potential of photonic devices for such emerging applications on a substrate material at chip levels strongly depends on the nanoscale manipulation of light; making the particular shapes and periodicity of the required photonic structures key parameters to control.
Silicon photonics has already demonstrated the potential of nanoscale photonic structures for improving internet broadband/telecommunications by enabling increases in data transfer rates from rack-to-rack via optical fiber-ribbon interconnections. But the extension of optical interconnection to the chip level with bare LSI chips for mass production at low cost has been somewhat hampered by the challenge to monolithically integrate the Si photonic chip with presently existing light sources. The difficulty rises from the incompatibility of Si, which is the backbone material choice at the optical and LSI chips level, with today’s compound semiconductor materials that are used for making laser diode light sources.
This presentation will provide an overview of current techniques that are being explored for channeling the light from remote semiconductor laser sources through photonic waveguides and various other functional elements in the optical chip level. Concluding remarks regarding future prospects for the monolithic integration will be highlighted.

BIO: O. Eknoyan is a Professor of electrical and computer engineering at TAMU. His early work was in the area of Si semiconductor microwave sources, and gradually progressed toward guided wave devices at the optical band of the spectrum. His recent research interests have been focused in integrated optical devices for photonic networking applications.
