AB  - Abstract
In this work we present a structure consisting of a semiconductor sample immersed between two one-dimensional photonic crystals, designed with the aim to investigate the possibility to increase radiative lifetime in infrared photodetectors, i.e., to decrease the background radiation limit. Since we used a HgCdTe detector for the detection of CO2 laser radiation, we formed a defect in the front-side photonic crystal with the transmission peak on 10.6 mm. Our numerical calculations show that the 1-D photonic crystal structures at the front and at the back side of the semiconductor sample significantly increase the radiative lifetime in the photodetector.

AB  - Abstract
In this paper we propose a silicon UV flame detector for combustion systems. In gas burners the relative intensity of flame radiation is dominant in the ultraviolet region (below 0.35 μm). In the visible and infrared regions the relative intensity of radiation of the incandescent surfaces (black body) is several orders of magnitude greater than the gas flame radiation intensity. Therefore it is required that the flame detector has a much greater sensitivity in the ultraviolet region. The proposed detector is formed on n-type silicon on isolator wafer. In order to suppress sensitivity in the visible and the IR regions, the absorption region of the detector is greatly reduced, and a UV filter utilizing photonic crystal is designed. The p-n junctions are formed by very shallow diffusion of impurities. The contacts are made after the deposition of a thin oxide layer. The UV filter is then sputtered on the detector surface. The filter consists of a thin silver film (protected by MgF2), and a one-dimensional photonic crystal made of twelve pairs of NaF/Y2O3 layers. The photonic band gaps of the crystal should suppress the propagation of the light with wavelengths greater than 0.35 μm. For the detector active area of 5 mm2, the thickness of the silver layer of 0.13 μm and a dark current of 1 nA, the noise equivalent power at 0.32 μm is 4.23·10-13W/Hz1/2. The calculated flame signal to total signal ratio is 0.52.
