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. 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. literacy capability acara
