摘要
采用电子束蒸发和键合技术,制作了具有高反射率的、表面为薄层单晶Si的分布Bragg反射器。用标准光刻工艺在单晶Si薄层上制作出窄带谐振腔增强型(RCE)金属-半导体-金属(MSM)光电探测器,响应峰值波长分别在836、900、965和1 030 nm处,其中在900 nm处峰值半高宽为18 nm。该器件具有波长选择特性,可有效抑制相邻频道间的串扰,而且容易制成集成面阵。
Si distributed Bragg reflector with crystal Si thin film on the reflector was fabricated by electron beam evaporation and bonding techniques. Narrow band Si resonant-cavity -enhanced(RCE) metal-semiconductor-metal(MSM) photodetoctors were fabricated by standard photolithography with responsivity peaks at 836 nm,900 nm,965 nm and 1030 nm respectively. The full-width-at-half-maximum was about 18 nm at 900 nm. The wavelength selectivity of the device could eliminate crosstalk between channels, and the integrated array could be easily realized.
