The authors theoretically present a powerful method to enhance and modify the magnetic resonances in metamaterials by strongly coupling them to the optical modes of Fabry–Pérot (FP) cavities. Strong coupling between magnetic plasmons (MPs) and optical cavity modes is observed, manifested by the large anticrossing of the resonant positions in the reflection spectra. It results in two branches of hybridized...
We tailor the lasing modes in the vertical cavity surface-emitting laser into a crescent wave using a surface elliptical ring. The crescent wave was observed to be localized at the semi-major axis of elliptical ring.
We report on the demonstration of a sub-diffraction-limited plasmonic laser at UV region by using the ZnO nanowire based on the semiconductor-insulator-metal (SIM) structure. At 77K, the laser with a threshold power of about 76MW/cm2 and the wavelength of 373 nm with an extremely small mode area below ?2/1000 was realized.
GaN-based wide bandgap semiconductor materials have been widely applied in fabrication of optoelectronic devices such as LEDs and LDs. These photonic devices have many practical applications in solid state lighting, color display and high density optical data storage. In this article, we report the current status of GaN-based blue vertical cavity surface emitting lasers (VCSELs) and photonic crystal...
