INNOGLOBO project
„Deep ultraviolet laser diodes”
Programme Description
INNOGLOBO is an international programme of National Center for Research and Development. Polish innovators can more freely than before choose a foreign project partner, project subject, and implement projects with different budgets. The aim of the INNOGLOBO program is to provide support to Polish entities in their expansion into foreign markets in the development, adaptation or implementation of modern technological solutions in a broad geographical context.
Project amount: .... PLN
Project duration: 01.10.2023 - 01.10.2025
Project Partner: Cornell University, USA
Project Goal
The aim of the Project is to demonstrate nitride-based laser diodes (LDs) emitting light in the ultraviolet spectral range of UVC (250nm-280nm). We plan to grow and process edge emitting UVC laser diodes by the plasma assisted molecular beam epitaxy (PAMBE). The hydrogen free PAMBE allows the use of the innovative LDs UVC design concept containing tunnel junctions and air claddings. Due to the technological challenges in fabricating and doping of AlGaN layers with a high Al composition, UVC laser diodes are currently not commercially available. Replacing conventional UVC light sources with semiconductor lasers will significantly simplify the design of devices using UVC light. Laser diodes provide great ease and flexibility in forming an optical beam (high power, parallel beam), which enables their use in many areas: (a) in medicine, it is used for virus detection and surface disinfection (COVID19), phototherapy of skin diseases, endoscopy, (b) in environmental protection - to detect contamination, to assess the quality of drinking water. (c) UVC laser diodes will replace the existing light sources used in semiconductor processing, in laser microscopes, as well as in the processes of sub-micron metal and graphene processing
