Abstract
Singlemode operation of first-order GaInP/AlGaInP DBR lasers at 635 nm is reported. The lasers were realised by one-step epitaxy and post-epitaxial structuring of surface gratings. The lasers with DBR grating periods between 97 and 100 nm show stable singlemode operation in the wavelength range 633.5 – 647.4 nm at room temperature and can be operated at up to 50°C.Keywords
