WebWe report the experimental results to continuously tune the coherence length of a semiconductor laser using an optical feedback scheme. The coherence length can be controlled by adjusting the feedback strength when a semiconductor laser operates in a coherence collapse regime. Fine structures of the fringe visibility of the laser output show …

The special features are …
WebIt is the purpose of this paper to review some topics related to the semiconductor lasers that use a waveguide resonant cavity extended beyond the solitary edge emitting laser. Such lasers are called "external cavity lasers" (ECL) or sometimes "extended cavity lasers" depending on subtle. differences in the structure and operation [9]. In this section, analytical expressions for RO frequency and damping for a rate equation model for a conventional, single-mode, class B QW laser model [54, 55] are derived. The QW rate equations are given by Here, {\mathcal {E}} is the slowly varying amplitude of the electrical field, which is normalized such that … See more Now, the solitary QD laser Eqs. (2.4) are analyzed starting with the steady states. For the subsequent analysis, the spontaneous emission in the field Eqs.
