摘    要:波片延迟片是光学系统中常用的一种重要光学器件。通常所指的λ/2和λ/4波片是对某特定波长而言的 ,当光波波长偏离该特定波长时 ,其位相延迟量也将随之发生变化。在光谱整形、激光调谐和光通讯等领域中经常使用宽带波片 ,它在一定带宽内的延迟量是相同的。国内大多数的厂商一般只能生产单波段波片 (带宽仅± 4 0nm) ,本文用计算机仿真设计了红外宽带高精度复合波片 ,采用石英晶体材料加工出来的复合波片性能与设计指标符合得较好。波片适用范围为 12 0 0~ 16 5 0nm ,中心波长为 1390nm ,λ/2 波片的位相延迟量范围为 180 .0°± 3.6°,λ/4波片的位相延迟量范围为 90 .0°± 3.6°,即相位延迟误差λ/10 0。

关 键 词:红外宽带复合波片  计算机仿真  光学系统  波片延迟片

Abstract:The waveplate is a usual but important component in optical system. Generally, λ/2 (or λ/4) waveplate is work at specifically wavelength. If the wavelength of the wave is not match to that of the waveplate, the phase retardation of wave would not π (or π/2). The broadband waveplate which the phase retardation is same in its bandwidth is widely used in spectrum shaping, laser tuning and optical communication. In this paper, an infrared three-stage waveplate is designed with the feature of wide band and high-resolution by the aid of computer simulation. The result of experiment turns to be high consistency with the design. The appropriate wavelength range of the waveplate is 1200~1650 nm. The central wavelength is 1390 nm. The phase retardation for λ/2 complex waveplate is 180.0°±3.6° and 90.0°±3.6° for λ/4 ones.
Keywords:applied optics  infrared  broadband  compound  waveplate  computer simulation
