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 …

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 …

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
… is presented. 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 …

From high power terahertz quantum cascade lasers to terahertz light amplifiers
… confined elements such as plasmonic lasers and nanolasers. This thesis also reports the development of fabrication techniques required to bring the aforementioned novel THz cavity designs from concepts to reality which include a high aspect ratio (> 1:10) anisotropic reactive-ion etch on GaAs …
