- This paper presents a novel solution to reduce the laser linewidth significantly in optical frequency combs using external optical feedback in gain switch semiconductor laser. This significant phenomenon will not only simplify the device structure but also enhance the spectral quality for high resolution metrology and optical sensing. This paper is part of our series of research findings using our novel external optical feedback (DOI:10.1109/JQE.2014.2378780). Other novel findings such as laser speckle reduction had underpinned many subsequent applications like machine vision with our industrial partner Global Laser Ltd and led to later KESS II PhD scholarship (Ref-21869).
