摘要

基于光通过弯曲波导的横向电（TE）和横向磁（TM）模式的不同传输损耗，本研究通过实验证明了一种具有低损耗和高波导宽度制造公差的横向电（TE）通偏振器。该偏振器采用350 nm i线光刻技术在铌酸锂薄膜平台上制造，在o波段内的插入损耗为13 dB（平均18.5 dB）。即使波导宽度在-200和+200 nm之间变化，这些特性也可以保持。

Large Fabrication Tolerance Transverse Electric-Pass Polarizer on Thin-Film Lithium Niobate Platform

Based on the different transmission losses of transverse electric(TE) and transverse magnetic (TM) modes of light passing through a bent waveguide, this study experimentally demonstrates a TE-pass polarizer with low loss and a high fabrication tolerance for the waveguide width. Fabricated on a thin-film lithium niobate platform using 350 nm i-line lithography, the polarizer exhibits an insertion loss of <1>13 dB (18.5 dB on average) within the O-band. These characteristics can be maintained even with waveguide width variations between -200 and +200 nm.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
