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...

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...
متن کاملCavity solitons in vertical-cavity surface-emitting lasers.
We investigate a control of the motion of localized structures (LSs) of light by means of delay feedback in the transverse section of a broad area nonlinear optical system. The delayed feedback is found to induce a spontaneous motion of a solitary LS that is stationary and stable in the absence of feedback. We focus our analysis on an experimentally relevant system, namely the vertical-cavity s...
متن کاملExploring ultrafast negative Kerr effect for mode-locking vertical external-cavity surface-emitting lasers.
We present analytical considerations of "self-mode-locked" operation in a typical vertical external-cavity surface-emitting laser (VECSEL) cavity geometry by means of Kerr lens action in the semiconductor gain chip. We predict Kerr-lens mode-locked operation for both soft- and hard-apertures placed at the optimal intra-cavity positions. These predictions are experimentally verified in a Kerr-le...
