Surface-emitting fiber lasers.
All fiber lasers to date emit radiation only along the fiber axis. Here a fiber that exhibits laser emission that is radially directed from its circumferential surface is demonstrated. A unique and controlled azimuthally anisotropic optical wave front results from the interplay between a cylindrical photonic bandgap fiber resonator, anisotropic organic dye gain, and a linearly polarized axial p...
متن کاملVertical Cavity Surface Emitting Lasers
The goal of this project was to increase the power of vertical cavity surface emitting lasers and to convert their wavelength into the blue/ultraviolet and the infrared for sensing applications. We have increased the power to the multi-watt level and have generated several milliwatts of blue light using optical pumping. Electrical pump has been less successful, but we have identified the proble...
متن کاملSpin-polarized surface-emitting lasers
We investigate the growth, fabrication, and characterization of an electrically-injected spin-polarized laser utilizing an Fe/n+-Al0.1Ga0.9As Schottky tunnel barrier for efficient spin injection into an InGaAs quantum well vertical-cavity surface-emitting laser. A threshold current reduction of 11% and maximum degree of circular polarization of 23% are observed for a 15 μm mesa diameter laser a...
متن کاملPlasma-based Surface Functionalization of Polystyrene Substrate
The method to modify the surface of polystyrene (PS) substrate for stable and versatile biomolecule immobilization was developed, which consists of two steps: 1) surface treatment by argon plasma irradiation to introduce hydroxyl group on PS and 2) covalent immobilization of vinylmethyleter-maleic acid copolymer (VEMAC) through a coupling reaction between hydroxyl group on plasma-irradiated PS ...
