An analysis for the broad-band absorption enhancement using plasmonic structures on uncooled infrared detector pixels
(SPIE, 2012-05)This paper introduces an analysis on the absorption enhancement in uncooled infrared pixels using resonant plasmon modes in metal structures, and it reports, for the first time in literature, broad-band absorption enhancement ... -
Broadband absorption enhancement in an uncooled microbolometer infrared detector
(SPIE, 2014)This paper introduces a method for a broadband absorption enhancement in the LWIR range (8-12 μm), in single layer microbolometer pixels with 35 μm pitch. For the first time in the literature, this study introduces a very ... -
Electrically controlled resistive switching assisted active ultra-broadband optical tunability in the infrared
(IEEE, 2013)We present an electrically tunable optical device with ultra-broadband tunability operating in 2-10 μm spectrum. We also, for the first time, optically observe resistive switching behavior in reflection measurements under ... -
