Lasers and optical amplifiers in the near- and short-wave infrared regions (700 nm to 3000 nm) are are a key enabling photonictechnology in modern technologies. They span many relevant technological windows such as telecommunications bands (1250 nmto 1625 nm), LIDAR wavelengths (905 nm & 1550 nm), eye-safe wavelengths (>1400 nm), and the NIR-IIc (1700 nm to 1880 nm), NIR-III(2080 nm to 2340 nm) biological windows and atmospheric gas sensing spectroscopy (~2000 nm). However, the integration oftraditional vacuum deposited semiconductor laser diodes and silicon microelectronics/photonics is notoriously difficult due tomaterial incompatibilities, preventing the very-large scale integration of these technologies and the development of on-chipquantum communication/information devices. Solution processed PbS colloidal quantum dots (CQDs) could better serve theseapplications in the infrared as they can be readily integrated into silicon technologies, lend themselves to cost-effective large scaleproduction of photonic devices and have tunable optoelectronic properties. However, the first generation of PbS lasers suffer fromlarge FWHM (~ 4 nm) and low q-factors, limiting their application. High q-factor cavities, such as those generated from plasmonicstrucures. are therefore also required to maximize the potential of PbS CQD lasers. The aim of this project will be to make a crucialstep in advancing PbS CQD laser technology for integrated photonics and explore their viability as future photonic devices, throughthe development of plasmonic caivites.

近波红外区域（700 nm至3000 nm）中的激光和光放大器是现代技术中的光对技术的关键。它们涵盖了许多相关的技术窗口，例如电信带（1250 nmto 1625 nm），激光雷达波长（905 nm＆1550 nm），眼部安全波长（> 1400 nm），以及NIR-IIC（1700 nm至1880 nm至1880 nm），nir-iir-ir-ir-ir-worter Windering and wasterieric and tosing and wasterric and to Senserierric and 2340 nmm，至2340 nmm，至2340 nmmm光谱法（〜2000 nm）。然而，由于体形不兼容性，传统真空的整合是沉积的半导体激光二极管和硅微电解/光子学的整合是困难的，从而阻止了这些技术的很大尺度整合以及偶像通信/信息设备的发展。溶液处理的PBS胶体量子点（CQD）可以更好地在红外线中使用这些pliplications，因为它们可以容易地集成到硅技术中，因此将其自身用于具有成本效益的光子设备的大尺度缩放量，并具有可调的OptoElectRonic属性。但是，第一代PBS激光器遭受了从LARGE FWHM（〜4 nm）和低Q因子遭受的限制，从而限制了它们的应用。高Q因子的腔，例如由质子疗法产生的腔。因此，还需要最大化PBS CQD激光器的潜力。该项目的目的是通过在等离子Caivites的开发中探索PBS CQD激光技术来提高PBS CQD激光技术的重要性。
