Abstract:

This phase I SBIR proposal comprises a feasibility study of an advanced new class of optical devices that promise to provide a dramatic expansion of practical optical function in areas such spectral filtering and optical processing. Many areas of opticaldata transport will benefit from robust, low-cost, yet high performance devices delivering building-block functionality in these areas. The new devices are fabricated using the powerful method of lithographic holography and are based on Holographic BraggReflectors (HBR's) as the primary functional element. In the present proposal, we focus on those aspects of HBR's performance key to their potential role as enabling elements in optical systems employing optical code-division multiple access (OCDMA).OCDMA offers important advantages for multiplexed optical data links including flexible bandwidth provisioning, all-optical channel discrimination, and multi-channel function with a single generic optical source. Lithographically scribed HBR's are broadlyenabling to OCDMA function and may comprise the key to reducing such systems to widespread use. Commercial and military activity is increasingly focused on the distribution of data. Optical data transport networks provide the key enabling element to suchactivity once high bandwidth and/or appreciable distances are involved. Optical Code Division Multiple Access Communications, an analog to microwave CDMA, offers powerful optical data transport function if suitable devices can be developed to render itsdeployment practical. The present proposal relates to the design, simulation, and system integration of a new class of optical coding devices which are based on holographic Bragg reflectors and fabricated via lithographic holography. These devices mayfinally open the door to deployment of OCDMA systems.
