The indirect wavelength selective thermal emitter that we have proposed is constructed using a new microheater, demonstrating the enhancement of the emission peak generated by the surface plasmon polariton. The thermal isolation is improved using a 2 μm-thick Si membrane having 3.6 and 5.4 mm outer diameter. The emission at around the wavelength of the absorption band of CO₂ gas is enhanced. The absorption signal increases, confirming the suitability for gas sensing. Against input power, the intensity at the peak wavelength shows a steeper increasing ratio than the background intensity. The microheater with higher thermal isolation gives larger peak intensity and its increasing ratio against the input power.
我们提出的间接波长选择性热发射器是使用新型微加热器构建的，证明了表面等离激元极化激元产生的发射峰得到增强。使用外径为3.6和5.4毫米的2微米厚硅膜改善了热隔离。在二氧化碳气体吸收带波长附近的发射得到增强。吸收信号增加，证实了其适用于气体传感。相对于输入功率，峰值波长处的强度比背景强度显示出更陡的增加率。具有更高热隔离的微加热器给出更大的峰值强度及其相对于输入功率的增加率。
