摘要

在这项工作中,我们简要回顾了带间级联激光器(ICL)的发展和现状,这些激光器与InAs/AlSb超晶格包层引起的长期问题有关。通过专注于混合包层方法来缓解这些问题,我们证明了与早期报道的类似设计的ICL相比,ICL在3-4µm波长区域的器件性能显著提高。这些改进包括在300K下宽面积器件的阈值电流密度低至134A/cm2,并且降低了阈值电压,峰值电压效率为80%,这比从先前报道的ICL获得的峰值电压效率高出10%以上。此外,我们已经证明了宽面积器件的连续波(cw)操作高达278K,这是外延侧上安装的宽面积II型ICL中最高的连续波操作温度,这意味着混合包层方法改善了散热。此外,通过对空穴注入器中具有不同GaSb层厚度的ICL进行比较研究,我们揭示并讨论了载流子输运、阈值电压和空穴诱导吸收损耗之间的有趣相关性,这可能有助于指导器件在目标温度范围内的优化操作。

Improved device performance of interband cascade lasers with hybrid cladding layers operating in the 3–4 µm wavelength region

In this work, we briefly review the development and status of interband cascade lasers (ICLs) as related to long-standing issues due to the InAs/AlSb superlattice cladding. By focusing on a hybrid cladding approach to alleviate these issues, we demonstrate substantially improved device performance of ICLs compared to earlier reported ICLs of a similar design in the 3–4 µm wavelength region. These improvements include a threshold current density for broad-area devices as low as 134 A/cm2 at 300 K and reduced threshold voltage with a peak voltage efficiency of 80%, which is more than 10% higher than that obtained from previously reported ICLs. Moreover, we have demonstrated continuous wave (cw) operation of a broad-area device up to 278 K, the highest cw operating temperature among epi-side up mounted broad-area type-II ICLs, implying improved thermal dissipation with the hybrid cladding approach. Additionally, by conducting a comparative study of ICLs with different GaSb layer thicknesses in the hole injector, we reveal and discuss an interesting correlation between the carrier transport, threshold voltage, and hole-induced absorption loss, which may help to guide device optimization for operation in a targeted temperature range.

期刊介绍: This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
