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...

are maintained. If the etching depth is equal to an integral number of half-wavelengths, uniformly high reflectivity across the active L. Fan, M.C. Wu, H.C. Lee and P. Grodzinski . mesa is achieved. 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 کاملCompositional grading in distributed Bragg reflectors, using discrete alloys, in vertical-cavity surface-emitting lasers
We present experimental results on a technique for alloy composition grading within distributed Bragg reflectors (DBRs) for use in vertical-cavity, surface-emitting lasers (VCSELs). This technique, implemented using molecular beam epitaxy (MBE), employs multiple group-III sources, with different fluxes, to realize a set of AlxGa1 xAs compositions without changing cell temperatures. By varying t...
