A Low-Threshold Miniaturized Plasmonic Nanowire Laser with High-Reflectivity Metal Mirrors

Plasmonic Waveguide-Integrated Nanowire Laser

Next-generation optoelectronic devices and photonic circuitry will have to incorporate on-chip compatible nanolaser sources. Semiconductor nanowire lasers have emerged as strong candidates for integrated systems with applications ranging from ultrasensitive sensing to data communication technologies. Despite significant advances in their fundamental aspects, the integration within scalable phot...

Low threshold gain metal coated laser nanoresonators.

We introduce a low refractive index layer between the metal and the gain medium in metal-coated laser resonators and demonstrate that it can significantly reduce the dissipation losses. Analysis of a gain medium waveguide shows that for a given waveguide radius, the low index layer has an optimal thickness for which the lasing threshold gain is minimal. The waveguide analysis is used for the de...

A theoretical investigation of the laser damage threshold of metal multi-dielectric mirrors for high power ultrashort applications.

An approach for the theoretical evaluation of the damage threshold in optical interference coatings that combine metal and dielectric films is presented. The model that is used combines a matrix formalism to describe the film system with the two temperatures model that describes the energy transfer and the temperatures of electrons and lattice in a solid submitted to a laser irradiation at the ...

An Analytical Model for Rare Earth Doped Fiber Lasers Consisting of High Reflectivity Mirrors

The present article is concerned with an analytical solution for some parts of rare earth doped fiber laser equations. The presented model is valid for both four and three-level fiber lasers consisting high reflectivity mirrors. A typical method to obtain initial value in the numerical solutions of fiber laser equations is shooting method, which is based on an iteration process. Whereas this st...
