Nano-Scale Effects in GaN-based Light-Emitting Diodes

Piprek J., Nakamura S., University of California, US

We here investigate the effects of built-in polarization on the properties of non-symmetric InGaN quantum wells. The impact of these nano-scale effects on the performance of blue light emitting diodes is analyzed utilizing advanced numerical [...]

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 [...]
