Lasing at exciton transition in optically pumped gallium nitride nanopillars.
We report the observation of room temperature lasing action in optically pumped GaN nanopillars. The nanopillars were fabricated by patterned etching and crystalline regrowth from a GaN substrate. When nanopillars were optically excited, a narrow emission peak emerged from the broad spontaneous emission background. The increasing rate is nine times faster than that of the spontaneous emission b...
متن کاملHigh-power diode-pumped fiber laser operating at 3 μm.
A high-power diode-cladding-pumped Ho³⁺-doped fluoride glass fiber laser operating in cascade mode is demonstrated. The ⁵I₆→⁵I₇ and ⁵I₇→⁵I₈ laser transitions produced 0.77 W at a measured slope efficiency of 12.4% and 0.24 W at a measured slope efficiency of 5.2%, respectively. Using a long fiber length, which forced a large threshold for the ⁵I₇→⁵I₈ transition, a wavelength of 3.002 μm was mea...
متن کاملSub-mA threshold 1.3 μm CW lasing from electrically pumped micro-rings grown on (001) Si
We demonstrate the first electrically pumped quantum-dot micro-ring lasers epitaxially grown on (001) silicon. Continuous-wave lasing around 1.3 μm was achieved with ultra-low thresholds as small as 0.6 mA and maximum operation temperatures up to 100°C. OCIS codes: (230.5590) Quantum-well, -wire and -dot devices; (140.5960) Semiconductor lasers; (140.3948) Microcavity devices; (160.3130) Integr...
متن کاملElectrically pumped waveguide lasing from ZnO nanowires.
Ultraviolet semiconductor lasers are widely used for applications in photonics, information storage, biology and medical therapeutics. Although the performance of gallium nitride ultraviolet lasers has improved significantly over the past decade, demand for lower costs, higher powers and shorter wavelengths has motivated interest in zinc oxide (ZnO), which has a wide direct bandgap and a large ...
متن کاملOptically pumped distributed feedback dye lasing with slide-coated TiO₂ inverse-opal slab as Bragg reflector.
We demonstrate an optical amplification of organic dye within a TiO2 inverse-opal (IO) distributed feedback (DFB) reflector prepared by a slide-coating method. Highly reflective TiO2 IO film was fabricated by slide coating the binary aqueous dispersions of polystyrene microspheres and charge-stabilized TiO2 nanoparticles on a glass slide and subsequently removing the polymer-opal template. TiO2...
