Metal-cavity surface-emitting nanolasers
Metal-cavity surface-emitting micro/nanolasers are proposed and demonstrated. The design uses metals as both the cavity sidewall and the top/bottom reflectors and maintains the surface-emitting nature. As a result of the large permittivity contrast between the dielectric and metal, the optical …

Theoretical investigation of metal-cavity nanolasers and nanoLEDs and comparison with experiments
Using metal to confine light in a small cavity and to make a light-emitting device has been intensively investigated recently since it provides a new approach to reduce the size of light-emitting devices. In the presence of metal, the optical mode volume of either a dielectric mode or a plasmonic …

Surface-emitting lasers for communications: novel metal-cavity microlasers and high-contrast-grating tunable VCSELs
… The design of novel micro and nanolasers using metal cavities for optical confinement is discussed. Theoretical modeling of quantum-well and quantum-dot emission properties, as well as experimental characterization of their coupling with optical cavities, are presented. Lasing behavior of our …

Dielectric micro-cavity surface-emitting lasers
In recent years, various metal-cavity nano-lasers have been theoretically studied and experimentally realized because it is believed that their small sizes can actually bring large potential in the next-generation dense photonic integration and optical interconnects. However, the absorption loss in …

Novel nanolasers, nano-LEDs, and modal cutoff confinement light emitters
Semiconductor metal nanocavity lasers and light emitting diodes together with novel modal cutoff confinement light emitters are investigated for optical interconnection application in future dense photonic integrated circuits. Several different cavity structures are designed, processed, and …

Development of nanoplasmonic devices for biosensing applications
… layer, such that the final device consists of a metal-insulator-metal cavity embedded in the 3D nanocup array. The spectral properties of this device include a sensitive, on-resonance, relative change in transmission intensity with a refractive index change without a spectral shift and spectral …

Excitation, Interaction, and Scattering of Localized and Propagating Surface Polaritons
… part, the surface plasmon resonance (SPR) of metal nanoparticles is analyzed. This resonant collective oscillation of the free electrons in a metallic nanoparticle leads to an enhancement and confinement of the local electric field at optical frequencies. The local electric field can be …
