Abstract

Frequency selective structures, in particular gratings, are useful to create single-mode laser diodes, however they introduce losses which can be detrimental for many applications. A theoretical framework to design Discrete Mode Laser Diodes (DMLDs) using gratings with the lowest loss possible while still achieving single-mode operation, is developed. A version of DMLDs using surface gratings is then designed and fabricated in Bragg reflection lasers (BRLs), which support second order nonlinear conversion within the laser cavity. These DMLDs show single mode operation with

efficiency is then performed to demonstrate the ability of the DMLD to support parametric optical processes within diode laser cavities.

离散模式激光二极管：非线性光学中的设计方程与应用

频率选择性结构，特别是光栅，对制造单模激光二极管非常有用，但它们会带来损耗，这对许多应用都是不利的。我们开发了一个理论框架，利用损耗尽可能低的光栅设计分立模式激光二极管（DMLD），同时还能实现单模运行。然后在布拉格反射激光器（BRLs）中设计和制造了使用表面光栅的 DMLDs 版本，该版本支持激光腔内的二阶非线性转换。这些 DMLD 显示出单模运行，具有 $>$40 dB SMSR、0.22 nm/mA 和 0.49 nm/$^\circ$C 电流和温度可调性。随后，还进行了效率为 59.8%W $^{-1}$ cm$^{-2}$ 的差分频率生成，以证明 DMLD 能够支持二极管激光腔内的参量光学过程。

期刊介绍： Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
