Semiconductor Laser Linewidth Theory Revisited [PDF]
Applied Sciences, 2021 More and more applications require semiconductor lasers distinguished not only by large modulation bandwidths or high output powers, but also by small spectral linewidths.

Rate-equation theory of a feedback insensitive unidirectional semiconductor ring laser
Optics Express, 2018 For our recently designed continuous-wave and single-frequency ring laser with intra-cavity isolator, we have formulated a rate-equation theory which accounts for two sources of mutual back-scattering between the clockwise and counterclockwise modes, i.e.

Theory of microscopic semiconductor lasers with external optical feedback
Optics Express, 2021 The properties of microscopic semiconductor lasers with external optical feedback are theoretically analysed. The size-dependence of the critical feedback level, at which the laser first becomes unstable, is clarified, showing how the dominant indicator of feedback stability is the gain of the laser, irrespective of size.

Theory of passively mode-locked photonic crystal semiconductor lasers
Optics Express, 2010 We report the first theoretical investigation of passive mode-locking in photonic crystal mode-locked lasers. Related work has investigated coupled-resonator-optical-waveguide structures in the regime of active mode-locking [Opt. Express 13, 4539-4553 (2005)].

Small-Signal Theory and Design of Traveling-Wave Semiconductor Cascade Lasers
IEEE Photonics Journal, 2010 Traveling-wave semiconductor cascade lasers (TWSCLs) are a form of series cascade laser (SCL) in which series-connected laser diodes are interconnected with commensurate transmission lines to create a periodically loaded structure.

Measurement of the emission spectrum of a semiconductor laser using laser-feedback interferometry
Scientific Reports, 2017 The effects of optical feedback (OF) in lasers have been observed since the early days of laser development. While OF can result in undesirable and unpredictable operation in laser systems, it can also cause measurable perturbations to the operating ...
