Spectral width of laser generation in quantum dot lasers: An analytical approach
- St. Petersburg Academic University-Nanotechnology Research and Education Center, Russian Academy of Sciences (Russian Federation)
An analytical approach to description of broad spectra of lasing in quantum-dot lasers has been developed. It is shown that the spectral width of the laser generation is determined by three parameters: the spectral width of the gain spectrum, homogeneous broadening of the line, and the effective parameter of the gain saturation. As a result, the dependence of the spectral width of lasing on the laser output power is shown to be universal and can be described as a function of a single dimensionless parameter.
