Claim 5:
6. The broadband tuning method of claim 5, wherein the step S1 comprises:
tuning the first light source within a first tuning range by the first forward grating region together with the first backward grating region to obtain a firstly-tuned first light source, and tuning the second light source within a second tuning range by the second forward grating region together with the second backward grating region to obtain a firstly-tuned second light source; and
tuning the firstly-tuned first light source within a third tuning range by the first phase region to obtain the tuned first light source, and tuning the firstly-tuned second light source within a fourth tuning range by the second phase region to obtain the tuned second light source.
