“…This is realized, e.g., in sol-gels doped with rareearth ions [1,10] or in polymers doped with dye molecules [11]. Alternatively, a gain medium can be deposited onto the cavity subsequent to the lithographic structuring, e.g., by spincoating [12][13][14] or sputtering [15].…”

Abstract:We investigate lasing from high-Q, polymeric goblet-type microcavities covered by an organic semiconductor gain layer. We analyze the optical modes in the high-Q cavities using finite element simulations and present a numerical method to determine the cutoff thickness of the gain layer above which the whispering gallery modes are strongly confined in this layer. Fabricated devices show reduced lasing thresholds for increasing gain layer thicknesses, which can be explained by a higher filling factor of the optical modes in the gain layer. Furthermore, reduced lasing threshold is accompanied by a red-shift of the laser emission.

“…2c). The normalised mode volume of 1.68 ( λ / n ) 3 is only twice as large as that of a silicon L3 cavity25 and, to our knowledge, represents an order of magnitude reduction in the mode volume of previously demonstrated polymer cavities192021. We find that in a hetero-waveguide cavity that the Q factor can be even greater, reaching a simulated Q factor as high as 19,000 due to gradual mode-matching in the cavity2627 (see Supplementary Information).…”

Polymers have appealing optical, biochemical, and mechanical qualities, including broadband transparency, ease of functionalization, and biocompatibility. However, their low refractive indices have precluded wavelength-scale optical confinement and nanophotonic applications in polymers. Here, we introduce a suspended polymer photonic crystal (SPPC) architecture that enables the implementation of nanophotonic structures typically limited to high-index materials. Using the SPPC platform, we demonstrate nanophotonic band-edge filters, waveguides, and nanocavities featuring quality (Q) factors exceeding 2, 300 and mode volumes (Vmode) below 1.7(λ/n)3. The unprecedentedly high Q/Vmode ratio results in a spectrally selective enhancement of radiative transitions of embedded emitters via the cavity Purcell effect with an enhancement factor exceeding 100. Moreover, the SPPC architecture allows straightforward integration of nanophotonic networks, shown here by a waveguide-coupled cavity drop filter with sub-nanometer spectral resolution. The nanoscale optical confinement in polymer promises new applications ranging from optical communications to organic opto-electronics, and nanophotonic polymer sensors.

“…When incoming light is in phase with light in a resonator that has completed a revolution around the structure, and resonance is achieved. Most applications of high Q resonators are based on the change of wavelength (frequency) shift of the WGM resonances excited by evanescent wave coupling and field intensity inside the resonator [8][9][10][11][12] . This requires exact coupling between the resonator and the adjacent waveguide or fiber.…”

A novel microdisk resonator sensor based on negative permeability metamaterials. The dispersion relationship of the cyllindrical waveguide coated with single negative metamaterials is obtained, and the resonant frequency and Q factor working at whisper-gallery-mode (WGM) is computed using finite element method (FEM), and agreement between theoretical results and simulation results is demonstrated to be good. Results show that the sensitivity of the sensor is significantly enhanced by the negative permeability metamaterials, and the Q factor can be tailored by adjusting the distance between the waveguide and the microdisk.
