Matrices of 960-nm vertical-cavity surface-emitting lasers
Matrices of vertical-cavity surface-emitting lasers with individual addressing of elements and radiation output through a gallium arsenide substrate are implemented. Individual laser emitters with a current aperture diameter of 6–7 μm exhibit continuous-wave room-temperature lasing at a wavelength o...

description | Matrices of vertical-cavity surface-emitting lasers with individual addressing of elements and radiation output through a gallium arsenide substrate are implemented. Individual laser emitters with a current aperture diameter of 6–7 μm exhibit continuous-wave room-temperature lasing at a wavelength of 958–962 nm with threshold currents of 1.1–1.3 mA, differential efficiency of 0.5–0.8 mW/mA, and a maximum output power of 7.5–9 mW. The parameter variation of individual emitters within a matrix chip containing 5 × 7 elements does not exceed ±20%. |
