Two-dimensional colloidal crystal corrugated waveguides.
We demonstrate, for what is to our knowledge the first time, two-dimensional (2D) corrugated waveguides at optical wavelengths obtained by use of 2D colloidal crystals. We report experimental studies of light coupling into and out of the waveguide structure. The diffracted light shows interesting optical properties that exist only in such 2D grating structures. Field distribution of the fundame...
متن کاملGiant colloidal diffusivity on corrugated optical vortices.
A single colloidal sphere circulating around a periodically modulated optical vortex trap can enter a dynamical state in which it intermittently alternates between freely running around the ringlike optical vortex and becoming trapped in local potential energy minima. Velocity fluctuations in this randomly switching state still are characterized by a linear Einstein-like diffusion law, but with...
متن کاملTwo-dimensional colloidal crystal heterostructures
We developed a simple method to fabricate colloidal crystal heterostructures (CCHs) with two or three stacked poly(methyl methacrylate) (PMMA) particle two-dimensional (2D) colloidal monolayer arrays of different particle spacings that independently diffract light. The 2D colloidal monolayer arrays of PMMA were prepared by using the air/water interface self-assembly method we recently developed...
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 کاملThe Anomalous Infrared Transmission of Gold Films on Two-Dimensional Colloidal Crystals
Tailoring optical response using periodic nanostructures is one of the key issues in the current research on functional composite materials. The anomalous light transmission through metallic films that have a regular array of submicrometer holes has stimulated much interest. This interest stems from both the underlying physics and also the perceived potential for applications in nanophotonics, ...
