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. WebApr 1, 2024 · The detuned loading effect can also be obtained by using an in-cavity etalon filter with 3% coating, as shown in Fig. 6(b). The lasing mode is located at the steep slope of a ripple, and a strong detuned-loading effect can be produced. Fig. 6(b) also shows a lack of detuned-loading effect in a passive feedback laser with HR coating.
