Wide-Aperture Diode Laser with Vertical Cavity
摘要
Abstract
A new type of diode laser with a scalable (fundamentally unlimited) aperture for the output optical beam has been proposed and calculated. Such an aperture can be implemented due to the use of a vertical cavity with one of the mirrors in the form of a surface diffraction grating. The threshold current density and differential efficiency of the proposed laser are calculated for the material parameters characteristic of the InGaAs/AlGaAs heterostructure and the spectral range at 0.98 µm.
