For a microcrystalline SiC thin-film thermal emitter in a cavity-coupled setup (a), a platinum heater ring (b) heats the suspended thermal emitter structure while minimizing conductive losses into the surrounding substrate. The suspended region stays hot while the temperature shifts to blue (cold) in the nonsuspended region of the substrate (c). (Image credit: Columbia University)

Thin-film-based optical cavity coupling enhances broadband thermal emission

$A nonperiodic pinhole-based photon sieve widens the display angle of a lensless digital dynamic holographic display produced by a liquid-crystal-based spatial light modulator (SLM). At top, a dynamic holographic display without the nonperiodic photon sieve has a narrow viewing angle. At bottom, a holographic display with the nonperiodic photon sieve, which diffracts light at a high angle, has a larger viewing angle. The pinhole array in the sieve is made nonperiodic to avoid creating periodic arrays of diffraction artifacts. The researchers note that the holographic objects to be displayed need to appear within the shaded regions to prevent clipping.$
