Ultrafast polarization modulation in vertical cavity surface emitting lasers with frequency dependent current injection

We report on a polarization modulation in vertical cavity surface emitting lasers (VCSEL), based on RF electrical injection. Complex polarization dynamics in the single mode regime is studied as a function of RF frequency and power at different bias currents. It has been observed that the polarization state of the VCSEL can be altered by changing the frequency of RF current modulation. Time res...

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...

Vertical-cavity surface-emitting lasers with lateral carrier confinement

Introduction: Optics is a viable solution to address the limitations of copper-based electronics in short-distance interconnects [1]. In these compact systems, devices must meet the stringent requirements imposed by the power budget and the thermal restriction. Recently, VCSELs have received considerable interest for board and chip level interconnects owing to their small footprints, ease of fa...
