摘要

提出了一种基于硅片上嵌入二氧化硅的氮化硅制造平台。为窄线宽激光器制备了长布拉格光栅。在该平台上实现了带有蚀刻面芯片的窄阻带(0.2 nm)布拉格光栅。加热器已经集成在芯片上，允许调谐超过1.5纳米的布拉格波长。通过将其中一个Bragg光栅与反射半导体光放大器(R-SOA)对接耦合，获得了激光器并进行了测试。在这些激光腔上，我们获得了0.16 nm的连续调谐范围和1.5 nm的不连续调谐范围。

Silicon Nitride Bragg Grating with Joule Thermal Tuning for External Cavity Lasers

The paper presents a fabrication platform based on silicon nitride embedded in silica on silicon wafers. Long Bragg gratings have been fabricated for narrow linewidth lasers. A narrow stop-band (0.2 nm) Bragg gratings with etched facet chips is achieved in this platform. Heaters have been integrated on the chips allowing tuning of the Bragg wavelength over 1.5 nm. Lasers have been obtained and tested by butt-coupling of one of these Bragg gratings to a reflective semiconductor optical amplifier (R-SOA). On these laser cavities we obtained a continuous tuning range of 0.16 nm and a discontinuous tuning range of 1.5 nm.
