Narrow-band Midinfrared Thermal Emitter Based on Photonic Crystal for NDIR Gas Sensor

摘要：

A high performance plasmonic thermal emitter with narrow bandwidth emission property were proposed and fabricated. This emitter is based on a metal coated two-dimensional (2D) photonic crystal of air holes in a silicon substrate. The PC structure is found to be highly effective in suppressing the thermal emission, which can yield 2 orders of magnitude more efficient that conventional IR sources. Thermally isolated, uniformly heated emitters, with photonic crystal structure modified surfaces are exploited for narrowband spectral tuning in the infrared wavelength regime. The results show that narrow band spectral tuning is accomplished through control of the lattice constant of the PC patterns.
