Experimental results are presented on selection of high-order modes in broad aperture laser diode coupled with digital planar hologram (DPH). Computer-generated hologram DPH fabricated on waveguide core determines the spectrum and field distribution at the laser output. The technology allows a temperature-stable spectral narrowing down to 0.6 nm and a decrease of the far-field distribution width from 6.5° to 2°. These results open a novel route for increasing the brightness and wavelength temperature stabilization of high-power laser diodes by coupling with planar photonic circuit.
