Abstract

We have fabricated Ag/SiO2/Ag plasmonic thermal infrared (IR) emitters with different hexagonal lattice periods on flexible polyimide (PI) membranes. The high temperature resistance and comparable coefficient of thermal expansion with metallic films enabled the fabrication of plasmonic IR emitters on PI films. We have investigated the effects of temperature and mechanical strain on the spectral and structural properties of the flexible emitter. The low heat conductivity and low thermal mass of thin free standing PI substrates enables IR emitters with low power consumption (<1 W) and fast switching time (in the order of ten milliseconds).
