Functional single-chip light-to-frequency converter based on high-resistivity

Abstract

The prototype of single-chip light-to-frequency converter is described. This converter is a mesa-planar photoresistor structure based on high-resistivity gallium arsenide with an N-shaped current-voltage characteristic. The converter functionality and utility for optoelectronics are showed. The main characteristics are indicated. The advantages and limitations of the proposed converter under the present analogs are analyzed.
