Abstract
InGaAsP/InP butt-jointed, buried ridge DBR lasers, exhibiting a record 15 nm tuning range, have been realised using only a three-step MOVPE process. The highest number (38) ever reported of regularly spaced wavelength channels is obtained from a two-section DBR laser, in which the passive waveguide was optimised in terms of carrier-induced effective index change and active-passive coupling efficiency.Keywords
