7(d)). Light penetrating into the p and n cladding layer Basics of Semiconductor Diode Lasers 17 is not absorbed due to its wide bandgap. These three properties greatly decrease the threshold current density. Because charge carriers in heterojunction lasers are conﬁned to a much smaller region than in homojunction lasers, the change in index of refraction at the interface between the p GaAs and the p AlGaAs can provide a guiding eﬀect for the laser beam. This is known as index guiding. Double heterojunction structure provides even more control over the size of the active region, and also provides additional index of refraction variation that allows for guiding of the optical wave.
32, 5, pp. 455. Ishii et al. (1996). ﬁlter (VCF) laser seemed to be inherent. As shown in Fig. 10, the wide tuning range in this case is due to the enhanced tuning of the ﬁlter peak in a GACC, which is placed in the center of the VCF laser [Kim et. al. (1994)]. This enhanced tuning derives from the fact that the center frequency tunes as the index change in one guide relative to the diﬀerence in modal indexes between the two guides, rather than relative to the starting index, as in grating mirror or other phase shifting elements [Chuang and Coldren (1993)].
Fig. 4(c) shows the mirror loss dependence on the lasing wavelength, these curves could be shifted with phase and mirror loss by varying the injection current in each region. Therefore the wavelength of DBR could be tuned. In a speciﬁc example as shown in Fig. 4(c), the lasing mode changes from mode A to mode B with mode jumping. Three operating schemes are considered in the following, depending on the combination of Bragg wavelength and phase control. 1 Bragg wavelength control When only the Bragg wavelength is controlled, the lasing wavelength moves to the shorter wavelength with mode jumping.
