Cutoff-taper performance of substrate-edge excited optoelectronic switches

Abstract
Substrate-edge excited optoelectronic switches can effectively be controlled by optical absorption, so producing an electron-hole plasma wedge which is cut off at specific physics within the excited substrate region and their influence on the microwave considered in a detailed analysis. The numerical results can successfully be utilised to a and performance at cutoff-taper operation. Thus, excellent optoelectronic efficiency and ing capability along with high on/off signal ratios and small input/output reflection obtained.
