Abstract
The mode competition in a dual-wavelength quarter-wave coupled-cavity semiconductor laser is analyzed using Langevin noise-driven rate equations. The laser can achieve simultaneous emission of two optical modes as a doublet with the same threshold, while the frequency difference of the two lasing wavelengths can be tuned by the injection currents. The analytical expressions for the spectral positions of the doublet and the threshold gain are derived, and a numerical model based on Langevin noise-driven rate equations is established for the mode competition process with enhanced physical insight.
