Metasurface-stabilized optical microcavities

open access: yesNature Communications, 2023
Microcavities concentrate light in tiny volumes and are important, e.g., for semiconductor lasers and nonlinear optics. In this paper, metasurfaces are introduced to realize microcavities with arbitrary mode profiles.

Demonstration of ultra-high-Q small mode volume toroid microcavities on a chip [PDF]

open access: yesApplied Physics Letters, 2004
Optical microcavities confine light spatially and temporally and find application in a wide range of fundamental and applied studies. In many areas, the microcavity figure of merit is not only determined by photon lifetime (or the equivalent quality ...

Hybrid Tamm-cavity modes in photonic crystal with resonant nanocomposite defect layer [PDF]

open access: yesКомпьютерная оптика, 2020
Hybrid optical modes in a one-dimensional photonic crystal with a resonant nanocomposite defect bounded by a metallic layer are studied. The nanocomposite consists of spherical metallic constituents, that are distributed in a dielectric matrix ...

Room Temperature Polariton Lasing in Ladder‐Type Oligo(p‐Phenylene)s with Different π‐Conjugation Lengths

open access: yesAdvanced Photonics Research, 2021
Polariton lasing is coherent emission that originates from macroscopic accumulation of polariton population in the ground state and is a promising route toward efficient coherent light sources as population inversion is not necessary. Unlike most Wannier–

Semiconductor microcavities for enhanced nonlinear optics interactions [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2008
Semiconductor microcavities offer a unique way to enhance nonlinear optical processes through light confinement in space and time. In this article we review two different nonlinear optics semiconductor-based applications that benefit from the microcavity

Strongly Confining Light with Air-Mode Cavities in Inverse Rod-Connected Diamond Photonic Crystals

open access: yesCrystals, 2022
Three-dimensional dielectric optical crystals with a high index show a complete photonic bandgap (PBG), blocking light propagation in all directions. We show that this bandgap can be used to trap light in low-index defect cavities, leading to strongly ...
