Optical detectors and sources with merged holographic optical elements suitable for optoelectronic interconnects

摘要

A novel apparatus for optically interconnecting integrated circuits that reduces optical path alignment difficulties and enhances signal quality. The present invention employs one or more holographic optical elements adapted for directing one or more modulated beams of light. Because each holographic optical element is individually aligned with a respective photonic device, the present invention is free from registration run off that is associated with large dimension optical substrates employed in previous optical interconnect schemes. Accordingly, optical path alignment between transmitting photonic devices and receiving photonic devices is preserved.
