We report on a first successful operation of current-driven GaN photonic-crystal surface-emitting laser, which can operate in blue-violet wavelength regions at room temperature.
A parametric study of micro-fluidic photonic crystal vertical-cavity surface-emitting lasers is carried out which shows a larger fluid-induced wavelength shift with smaller lattice constant. An effective index model is developed which is consistent with measurements.
Lasing action of a composite organic thin-film laser with a 2nd-order two-dimensional photonic crystal structure of triangular lattice is investigated. The analysis of band theory is adopted and the emission pattern is also presented.
A photonic crystal fabricated into ion-implanted VCSELs can engineer the spatial overlap between the optical mode and gain for improved high speed operation and reduced relative intensity noise. The ion-implanted aperture should be les 4 um larger than the optical aperture to avoid excessive electrical parasitics.
We report experimental observation of nonlinear transverse optical pattern distributions in a photonic crystal surface-structured VCSEL by using near-field scanning optical microscope. Rotating cavity dipole solitons and vortex soliton clusters are demonstrated.
We report fabrication of GaN-based two-dimensional surface emitting photonic-crystal lasers and successful demonstration of lasing action at room temperature with the emission wavelength at 424.3 nm and a low threshold pumping energy density of 3.5 mJ/cm2.
