Lasing on surface states in vertical-cavity surface-emission lasers.

چکیده
We report experimental observation of lasing on surface states, in the form of standing waves at the termination of a defect-free photonic crystal on top of vertical-cavity surface-emission lasers. Direct images of lasing modes at the truncated periodic potential, along one side of a square lattice, are demonstrated by collecting near-field radiation patterns, as well as in numerical simulations. Our results provide a step toward realizing surface and edge states in optical cavities.

Surface-structure-assisted chaotic mode lasing in vertical cavity surface emitting lasers.
We demonstrate chaotic mode lasing in vertical cavity surface emitting lasers at room temperature, with an open cavity confined laterally by the native oxide layer. Instead of introducing any defect mode, we show that suppression of lower-order cavity modes can be achieved by destroying vertical reflectors with a surface microstructure. Lasing on chaotic modes is observed directly through colle...
متن کاملAnomalous above-threshold spontaneous emission in gain-guided vertical-cavity surface-emitting lasers
Anomalously large decrease in spontaneous emission is observed in gain-guided vertical-cavity surface-emitting lasers after the onset of lasing. By analyzing two-dimensional profiles of the lasing mode and carrier density, we found that this unexpected phenomenon originates from the contraction of transverse lasing mode size. Under the condition of the constant modal gain, it is explained that ...

متن کاملOn the importance of cavity-length and heat dissipation in GaN-based vertical-cavity surface-emitting lasers
Cavity-length dependence of the property of optically pumped GaN-based vertical-cavity surface-emitting lasers (VCSELs) with two dielectric distributed Bragg reflectors was investigated. The cavity lengths were well controlled by employing etching with inductively coupled plasma and chemical mechanical polishing. It was found that the lasing characteristics including threshold, slope efficiency...
متن کاملVarious high-order modes in vertical-cavity surface-emitting lasers with equilateral triangular lateral confinement.
Large-aperture vertical-cavity surface-emitting lasers with an equilateral triangular lateral confinement are fabricated to investigate the formation of high-order resonant modes. The experimental lasing patterns are composed of the superscar mode, honeycomb eigenstate, and chaotic mode. Experimental results confirm the theoretical predictions that tiny symmetry breaking can cause the high-orde...
