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 کاملLow current density, inverted polarity, high-speed, top-emitting 850 nm vertical-cavity surface-emitting lasers
High-speed, oxide-confined, inverted polarity (n-up), polyimide-planarised 850 nm vertical-cavity surface-emitting lasers (VCSELs) were fabricated and characterised. The lasers exhibit a 23 dB frequency modulation bandwidth ( f3dB) up to 15.2 GHz with a 10 mm oxide aperture diameter, at the lowest current density (Jbias) ever reported of 6.4 kA/cm . The ratio f3dB 2 /Jbias 1⁄4 36.1 (GHz/kA/cm) ...
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 کامل10.1 nm range continuous wavelength-tunable vertical-cavity surface-emitting lasers - Electronics Letters
A record wide continuous wavelength tuning range of IO.lnm is demonstrated in vertical-cavity surface-emitting lasers (VCSELs) with monolithically integrated thin-film metal heaters. Single longitudinal mode and single transverse mode are maintained throughout the tuning range. The thin-film heater can stand higher temperatures over a wider tuning range. It is also separated and electrically is...
