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 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 ...
