This joint proposal, between the Departments of Electrical Engineering and Physics at the University of Bristol, and the Physics Department at St Andrews University aims to use and enhance a facility for post-processing laser diodes so that new structures can be constructed for a wide range of applications. By using a high performance focused ion beam gun system with integral mass and optical spectrometers for in-situ etch monitoring, it is proposed to modify high quality commercial laser chips, for example by fabricating shaped partial or complete internal mirrors, gratings or selective lenses, while the device performance is being monitored. The main focus of the work be on the development of new laser structures with high quality modal control (as evidenced in the spatial and spectral domains) using advanced novel features including linear or curved partial or complete internal mirrors, gratings or selective lenses which can be precisely fabricated with high yields while the device performance is being monitored. The project will seek to address both edge emitting and vertical cavity surface emitting laser diodes as considerable applications exist for both types of device if they exhibit high beam quality, and as early research into both systems has been most promising.
