A study of reflex optoelectronic switching matrices and their derivatives
Abstract
The application of reflex optoelectronic switching matrices (ROSM) to signal processing in the GHz region is analyzed. Various signal processing functions such as delay generation, loop filtering, word generation/detection, integration and digital to analog conversions are identified and their respective realizations in a ROSM are presented. It is found that for dedicated signal processing functions, simpler submatrices instead of full matrices can be employed with significant reduction in complexity and cost. The performance of ROSMs using currently commercially available components confirms the feasibility of GHz signal processing with ROSMs.
