介绍了一种新型的集成TM通波导亚波长狭缝偏振器,并对其进行了理论分析。通过适当的缝隙设计,波导可以用作单偏振波导以仅引导光信号的TM偏振模式。用26 μ m的TM通偏振器的长度,我们的计算机模拟预测的插入损耗为0.54 dB的TM偏振模式的消光比为20.3 dB,在1.55 μ m的波长。(C)2005年,美国光学学会。
A novel integrated TM-pass waveguide polarizer with a subwavelength-wide slot is introduced and theoretically analyzed. With a proper design of the slot, the waveguide can be used as a single polarization waveguide to guide only TM polarization modes of the light signal. With 26 mu m length of this TM-pass polarizer, our computer simulations predict the insertion loss of 0.54 dB for the TM polarization mode with the extinction ratio of 20.3 dB at the wavelength of 1.55 mu m.
