Webdetuned loading concept, until now only having been applied to near-infrared emitting interband semiconductor lasers [13, 14]. Detuned loading is realised in a coupled cavity laser system by coup-ling a passive cavity to the active semiconductor laser such that frequency-dependent losses with a periodicity of the free-spectral WebWe then operate this ECL with minimum chirp by tuning the lasing mode to the longer wavelength limit of the stable operation region. This is because the detuned loading effect is maximized at this limit as the in-phase condition between the lights reflected from the PBR and anti-reflection (AR) coated facet of the gain medium is satisfied. the palm court sheraton park lane
