摘要

聚合物光子学由于具有广泛的集成光子应用和宽波长透明度的潜力而受到广泛关注。由于聚合物波导的低折射率对比度，晶圆级测试具有挑战性。在这篇文章中，我们展示了一种基于非晶硅的面外聚合物波导光栅耦合器。模拟预测最大效率为-1.13 dB，在c - l波段上具有95 nm的1 dB带宽。单模光纤与聚合物波导的峰值耦合效率为-2.15 dB /个，带宽分别为49 nm和89 nm，带宽为1 dB和3 dB。

High-efficiency broadband out-of-plane fiber-to-polymer waveguide grating coupler.

Polymer photonics is receiving significant attention due to its potential for a wide range of integrated photonic applications and wide wavelength transparency. Wafer-scale testing is challenging due to low-index contrast in polymer waveguides. In this Letter, we demonstrate an amorphous silicon based out-of-plane polymer waveguide grating coupler. Simulations predict a maximum efficiency of -1.13 dB, with a 1 dB bandwidth of 95 nm over the C-L-band. Experimentally measured peak coupling efficiency between a single-mode optical fiber and polymer waveguide is -2.15 dB per coupler with a 1 and 3 dB bandwidth of 49 and 89 nm, respectively.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
