A plasmonic quantum well laser may be provided. The plasmonic quantum well laser includes a plasmonic waveguide and a p-n junction structure extends orthogonally to a direction of plasmon propagation along the plasmonic waveguide. Thereby, the p-n junction is positioned atop a dielectric material having a lower refractive index than material building the p-n junction, and the quantum well laser is electrically actuated. A method for building the plasmonic quantum well laser is also provided.

The disclosure relates in some aspects to an open dielectric resonator with nanoparticles secured on its outer surface, where the nanoparticles are located, sized and/or shaped to increase an amount of backscattered light in the resonator to provide substantially lossless, coherent backscattering of light. In some examples, fine particles are used instead of nanoparticles. Other features relate to a laser system having a plasmon-activated cavity optically coupled to a laser where the plasmon-activated cavity is configured to (a) receive a laser beam, (b) scatter the laser beam in accordance with a plasmon resonance, and (c) feed at least a portion of the laser beam back to the laser for self-injection locking of the laser. The plasmon-activated cavity may be a dielectric resonator with surface particles configured to stabilize the laser to a frequency of a plasmon mode to reduce a linewidth of the laser.

Provided is a laser resonator for generating a laser light by absorbing energy from outside. The laser resonator includes a metal body and a gain medium layer having a ring shape. The gain medium layer of a ring shape may be provided on the metal body and may generate the laser light by a plasmonic effect.

A vehicle component, and a method and tool for forming the component are provided. First and second tools with first and second surfaces, respectively, are provided. The first tool is translated along a first axis towards the second tool such that the first and second surfaces cooperate to define a mold cavity configured to form an accessory mount feature with an aperture. The second surface is configured to form an integrated rib extending outwardly from an upper surface of the mount feature to a planar bearing surface surrounding the aperture with the planar bearing surface oriented at an acute angle relative to the upper surface. The first axis is substantially parallel to the upper surface.

A plasmonic light source includes a substrate and a square nano-cavity formed on the substrate. The nano-cavity includes a quantum well structure. The quantum well structure includes III-V materials. A plasmonic metal is formed as an electrode on the square nano-cavity and is configured to excite surface plasmons with the quantum well structure to generate light. Complementary metal oxide semiconductor (CMOS) devices are formed on the substrate.

A two-dimensional material plasmonic laser (device) is provided with a surface plasmonic cavity and an atomically thin semiconductor monolayer gain medium disposed on the surface plasmonic cavity. Under optical pumping or electrical pumping, the surface plasmonic cavity provides a laser feedback mechanism by coupling electron-hole pairs confined in the atomically thin semiconductor monolayer gain medium and the surface plasmon modes in the dark-mode surface plasmonic cavity, and a laser light is emitted from the two-dimensional material plasmonic laser.

The Hybrid Photonic Plasmonic Interconnect (HyPPI) combines both low loss photonic signal propagation and passive routing with ultra-compact plasmonic devices. These optical interconnects therefore uniquely combine fast operational data-bandwidths (in hundreds of Gbps) for light manipulation with low optical attenuation losses by hybridizing low loss photonics with strong light-matter-interaction plasmonics to create, modulate, switch and detect light efficiently at the same time. Initial implementations were considered for on-chip photonic integration, but also promising for free space or fiber-based systems. In general two technical options exist, which distinguished by the method the electric-optic conversion is executed: the extrinsic modulation method consists of an continuous wave source such as an LED or laser operating at steady power output, and signal encoding is done via an electro-optic modulator downstream of the source in the interconnect. In contrast, in the intrinsic method, the optical source is directly amplitude modulated.
