Abstract

This paper proposes a design for the monolithic high-contrast mirror designed for infrared radiation. We use a fully vectorial model to search for the construction parameters of semiconductor monolithic high-contrast grating (MHCG) mirror providing maximal power reflectance. Such mirror can play a role of optical coupler, being alternative for distributed Bragg reflectors (DBRs). DBRs for mid- and long-wavelength infrared radiation are technologically highly demanding in terms of uniform quarter-wavelength layers control. Our results comprise a complete image of possible highly reflecting MHCG mirror constructions for potential use in optoelectronic infrared devices and systems.
