Infrared radiation converter based on Fabry-Perot microresonators

Abstract

The methods of transformation of information from one spectral range to another based on Fabry– Perot microresonators are offered. The methods allow to minimize environmental temperature fluctuations influence on characteristics of one or two Fabry–Perot microresonators, which are transforming information from one spectral range to another. In the first case, minimization is performed when the initial temperature point of the microresonator corresponds to the maximum of the probing radiation intensity change depended on temperature. In the second case, minimization is performed when only one of two microresonators has a fixed shift of the initial temperature point.
