Congratulations to first author Alexander Ware and co-authors Morgan Bergthold, Noah Mansfield, and Zarko Sakotic, as well as collaborators at Sandia National Labs, on the publication of our paper: “Decoupling absorption and radiative cooling in mid-wave infrared bolometric elements“. By designing a mid-wave IR metal-insulator-metal resonator with an integrated long-wave IR epsilon near zero material, our thin film device can near-perfectly absorb normal incident MWIR radiation and release thermal energy in the LWIR, at grazing angles. We show that the basic design can be leveraged for ultra-thin (<200 nm) floating structures, offering a mechanism to decouple detection (in the MWIR) from radiative cooling (in the LWIR) for high performance bolometric detection.
