摘要

一种基于单角面(SAF)半导体激光二极管的可调谐980 nm外腔激光器，不需要增透涂层或额外的外反射镜。SAF激光二极管由一个弯曲的脊状波导组成，该波导在一个侧面与小面解理面正常相交，在另一个侧面呈一定角度相交。通过将低反射率角度面(R = 2 × 10-5)输出耦合到衍射光栅，获得了宽调谐范围(70 nm)的外腔激光器。

Single-angled-facet laser diode for tunable external cavity lasers

A tunable 980 nm external cavity laser based upon a single-angled-facet (SAF) semiconductor laser diode is demonstrated that does not require anti-reflection coatings or additional external mirrors. The SAF laser diode is comprised of a curved ridge waveguide that intersects the facet cleavage plane normally at one facet and at an angle at the other facet. A wide tuning range (70 nm) external cavity laser was obtained by coupling the output from the low reflectivity angled facet (R = 2 x 10-5) to a diffraction grating.
