Fano Resonance Membrane Reflectors from Mid-Infrared to Far-Infrared

Abstract

We report here single layer ultra-compact Fano resonance photonic crystal membrane reflectors at mid-infrared and far-infrared bands, based on single layer crystalline Si membranes. High performance reflectors were designed for surface-normal incidence illumination with center operation wavelengths of 1.5 um, 8 um, and 75 um, respectively. Large area patterned membrane reflectors were also fabricated and transferred onto glass substrates based on PDMS stamp assisted membrane transfer processes. Close to 100% reflection was obtained at ~76 um, with a single layer Si membrane thickness of 18 um. Such Fano resonance based membrane reflectors, offer great opportunities for high performance ultra-compact dielectric reflectors at infrared and THz regions.
