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. WebNov 30, 2015 · 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. Thus, by using this method together with conventional wavelength-locking algorithm, we can operate this ECL with minimum chirp at any ...

Webmaximum bandwidth by the detuned loading effect [9, 10]. The ECL parameters used in this evaluation are listed in Table 1. The results in Fig. 1(b) show that the 3-dB modulation bandwidth of this ECL can be increased to >6.6 GHz when Lext is <3 mm. Thus, to fabricate an ECL operating at 10 Gb/s, it is required to set Lext to be <3 mm. This can ...
