Tunable resonant optical microcavities by self-assembled templating.
Micrometer-scale optical cavities are produced by a combination of template sphere self-assembly and electrochemical growth. Transmission measurements of the tunable microcavities show sharp resonant modes with Q factors of >300 and 25-fold local enhancement of light intensity. The presence of transverse optical modes confirms the lateral confinement of photons. Calculations show that submicrom...
متن کاملTunable optical activity of plasmonic dimers assembled by DNA origami.
We investigate the optical response of gold nanorod (AuNR) dimers assembled in parallel on a DNA origami template. Plasmonic circular dichroism (CD) was found to be highly dependent on the orientation of the dimers relative to the DNA axis and the inter-rod distances. Dipole-dipole distances play a critical role in the induced plasmonic chirality. The orientation dependence of induced CD was fu...
متن کاملTwo-Dimensional Metal–Chalcogenide Films in Tunable Optical Microcavities
Integration of quasi-two-dimensional (2D) films of metal-chalcogenides in optical microcavities permits new photonic applications of these materials. Here we present tunable microcavities with monolayer MoS2 or few monolayer GaSe films. We observe significant modification of spectral and temporal properties of photoluminescence (PL): PL is emitted in spectrally narrow and wavelength-tunable cav...

متن کاملSagnac Effect in Resonant Microcavities
The Sagnac effect is the phase difference between two counter-propagating laser beams in the same ring resonator due to rotation, originally introduced by Sagnac in 1913[1]. It has become the basis for the operation of the optical gyroscopes such as ring laser gyroscopes and fiber optic gyroscopes after the invention of lasers and optical fibers in 1970’s [2, 3, 4, 5] because the phase and freq...
