dc.description.abstract | We report a GaN-based VCSEL with a high-contrast grating (HCG) as the top mirror. The HCG consisted of TiO2 and rested directly on the n-GaN without an airgap or the use of any DBR layers to boost the reflectivity. The full VCSEL structure was optically pumped at room temperature and showed a lasing threshold of approximately 0.69MW/cm(2) and a lasing wavelength at 369.1 nm. This first demonstration of lasing in a HCG GaN based VCSEL opens up the possibility to explore all the potential benefits of HCGs in the blue and ultraviolet spectral regime. | en_US |
