Abstract :
This paper demonstrated diodes that incorporate an internal diffraction grating that provides frequency selective feedback to narrow the output spectrum and ensure that the emitter operates at the desired pump wavelength. Paper also presents the light current characteristics of a 1908 nm 18 emitter (9mm) bar mounted on a conductively-cooled mount. The power versus current performance shows 10W output at 50A, with a spectral width <;3 nm FWHM.
