Tunable laser diodes pdf files

So far, the most successful tunable laser diodes include ring-based lasers [ 6], distributed Bragg reflector (DBR) lasers [36], DFB lasers [37]in- tegrated on Si through wafer bonding, sampled-grating distributed Bragg reflector (SG-DBR) lasers [38], and superstructure grating (SSG) DBR lasers [39] through regrowth steps on native substrates.
