Abstract :
We have fabricated single mode lasers with lateral gratings by focused ion beam lithography. The transmission of the DFB mode through a passive unpumped waveguide section was studied as a function of the emission wavelength. The lateral grating was also investigated as a passive Bragg filter by pumping the unpatterned waveguide section. Ridge waveguides were fabricated on InGaAsP/InP laser structures with 8 compressively strained quantum wells.
