Anti-Crossing Levels and Electron Tunneling in Quantum Rings

Filikhin I., Matinyan S.G., Nimmo J., Vlahovic B., North Carolina Central University, US

Quantum Rings (QR) attracted attention during the last decade because of remarkable meso and nano-structures, due to non-simple connected topology. In our work [3] it was shown that in the weakly coupled double concentric quantum [...]

Lateral-Cavity Design for Long-Wavelength Vertical-Cavity Lasers

Piprek J., Bregy A., Jayaraman V., Chiu Y-J, Bowers J., University of California, US

For more than a decade, long-wavelength vertical-cavity lasers (VCLs) for fiber-optic applications are subject of intense research efforts. GaAs-based VCLs emitting at shorter wavelength (0.85-micron) have been commercialized successfully, however, the challenge of transferring this [...]
