Vertical Cavity Surface Emitting Lasers
The goal of this project was to increase the power of vertical cavity surface emitting lasers and to convert their wavelength into the blue/ultraviolet and the infrared for sensing applications. We have increased the power to the multi-watt level and have generated several milliwatts of blue light using optical pumping. Electrical pump has been less successful, but we have identified the proble...

متن کاملSpin-polarized surface-emitting lasers
We investigate the growth, fabrication, and characterization of an electrically-injected spin-polarized laser utilizing an Fe/n+-Al0.1Ga0.9As Schottky tunnel barrier for efficient spin injection into an InGaAs quantum well vertical-cavity surface-emitting laser. A threshold current reduction of 11% and maximum degree of circular polarization of 23% are observed for a 15 μm mesa diameter laser a...
متن کاملHigh frequency continuous birefringence-induced oscillations in spin-polarized vertical-cavity surface-emitting lasers.
Sustained, large amplitude and tunable birefringence-induced oscillations are obtained in a spin-vertical cavity surface-emitting laser (spin-VCSEL). Experimental evidence is provided using a spin-VCSEL operating at 1300 nm, under continuous-wave optical pumping and at room temperature. Numerical and stability analyses are performed to interpret the experiments and to identify the combined effe...

The top electrodes which simultaneously pump the phase-shifted and non-phase-shifted region are then deposited by evaporation and lift-off processes. Fig. 2 shows the scanning electron micrograph (S...
