These devices show the advantage of a considerably simplified fabrication process compared to conventional tunable laser types. The lasers comprise an active Bragg reflector integrated with an uncorrugated separately pumped gain region. By adjusting the current through the Bragg reflector, the wavelength can be tuned between 1590.8 and 1595.2 nm.}, language = {en} } @article{SchreinerKoerblGraebeldingeretal., author = {Schreiner, Rupert and K{\"o}rbl, M. and Gr{\"a}beldinger, H. and Gentner, Jean-Louis and Schweizer, H.}, title = {Laterally gain-coupled 1.57 [micro sign]m DFB lasers with chromium surface grating and self-aligned Ti/Pt/Au ohmic contact}, series = {Electronics Letters}, volume = {36}, journal = {Electronics Letters}, number = {7}, publisher = {The Institution of Engineering and Technology, IET}, issn = {0013-5194}, doi = {10.1049/el:20000500}, pages = {636 -- 637}, abstract = {A simple method for fabricating gain coupled DFB lasers with lateral surface chromium Bragg gratings and self-aligned low capacitance ohmic contacts is reported.
