WebNov 1, 2013 · The effect of phase-sensitive optical feedback is directly visible from Fig. 2, ... Detuned loading is realised in a coupled cavity laser system by coupling a passive cavity to the active semiconductor laser such that frequency-dependent losses with a periodicity of the free-spectral range of the passive cavity are introduced. WebDec 30, 2024 · In the red-detuned region, γ r is enhanced and α is reduced, so the whole critical feedback value R c r i t is improved. In the blue-detuned region, all the trends are opposite, R c r i t is declined. The detuned loading effect on γ r and α is the main reason for the high feedback tolerance of a red-detuned DBR laser. Webdetuned loading concept, until now only having been applied to near-infrared emitting interband semiconductor lasers [13, 14].
