Reduction of residual excess noise in class-A lasers using two-photon absorption

Abstract : We demonstrate experimentally a significant reduction of the remaining excess intensity noise in a class-A semiconductor laser. This is obtained by inserting into the laser cavity a buffer reservoir mechanism based on two-photon absorption in GaAs. The excess noise peaks at the laser-free spectral range, induced by the beating between the lasing mode and the amplified spontaneous emission in the adjacent non-oscillating modes, is reduced by 20 dB, while preserving the class-A dynamical behavior of the laser cavity. © 2016 Optical Society of America.
