基于固体腔的超窄带F—P干涉滤光片

基于固体腔的超窄带F—P干涉滤光片黎明 胡必春 聂明局华中科技大学光电子科学与工程学院,湖北武汉430074摘　要:介绍了一种利用熔融石英作为间隔层来实现F—P超窄带干涉滤光片的设计原理与方法。并制备了半宽2nm，透射率约90％的滤光片。该滤光片间隔层的干涉级次很高，能有效压缩带宽，实现超窄带滤波，不但极大提高了峰值透射率，而且温度稳定性好。[著者文摘]

The filter that 3dB bandpass is 2nm, transmission ratio about 90% is produced. Interference order of this filter is high, so the ultra-narrow band-pass can be achieved, transmission ratio is increased, and temperature stability is good.[著者文摘]
