Significant progress has been made in III-nitride-based lighting technologies in the past decades. Owing to excellent and unique properties, including direct, tunable energy bandgaps (from short UV to longer infrared wavelengths), III-nitride (GaN and its alloys) is the material of choice for today's massive light-emitting diode (LED) based solid-state lighting technology. Despite this huge success, there are still many critical challenges to overcome. For example, III-nitride LEDs still exhibit low efficiency in the green and red spectral wavelengths; even blue LEDs show an efficiency drop when operated at a high current. These challenges can be by and large solved by growing these materials defects free using plasma-assisted molecular beam epitaxy. Furthermore, the efficiency-related problems associated with the current LED technology can be addressed byelectrically injected laser diodes (LDs). In this international collaboration, Dr. Muziol will grow device quality III-nitrides materials and Dr Sadaf will fabricate the devices.This Alliance international catalyst grant will be an essential first step to developing compact, high efficiency, full-colour laser diodes. The laser diodes will be valuable for a range of essential applications, including solid-state lighting, AR/VR, display, LIDAR, and photonic integrated circuits. The development of full-color lasers will establish Canada as a leading player in the worldwide photonics sector. The HQPs will get hands-on exposure to state-of-the-art growth and fabrication facilities. Therefore, the HQPs involved in this project will be highly benefitted and will be assets to Canadian academia and the photonics job market.

在过去的几十年中，基于III族氮化物的照明技术已经取得了重大进展。由于其优异和独特的性能，包括直接的可调能带隙（从短紫外到长红外波长），III族氮化物（GaN及其合金）是当今基于大规模发光二极管（LED）的固态照明技术的首选材料。尽管取得了巨大成功，但仍有许多关键挑战需要克服。例如，III族氮化物LED在绿色和红色光谱波长中仍然表现出低效率;甚至蓝色LED在高电流下工作时也表现出效率下降。这些挑战可以通过使用等离子体辅助分子束外延无缺陷地生长这些材料来解决。此外，与当前LED技术相关的效率相关问题可以通过电注入激光二极管（LD）来解决。在这项国际合作中，Muziol博士将培育出器件质量的III族氮化物材料，Sadaf博士将制造这些器件。这项联盟国际催化剂资助将是开发紧凑、高效、全色激光二极管的重要第一步。激光二极管将在一系列重要应用中发挥重要作用，包括固态照明、AR/VR、显示器、LIDAR和光子集成电路。全色激光器的发展将使加拿大成为全球光子学领域的领先者。HQP将亲自接触最先进的生长和制造设施。因此，参与该项目的HQP将受益匪浅，并将成为加拿大学术界和光子就业市场的资产。
