We demonstrate a silicon nitride trench waveguide deposited with bowtie antennas for plasmonic enhanced optical trapping. The sub-micron silicon nitride trench waveguides were fabricated with conventional optical lithography in a low cost manner. The waveguides embrace not only low propagation loss and high nonlinearity, but also the inborn merits of combining micro-fluidic channel and waveguid...

To enhance lasers’ power and improve their performance, a model wasapplied for the waveguide design of 400 nm InGaN/InGaN semiconductor laser, whichis much easier to implement. The conventional and new laser structures weretheoretically investigated using simulation software PICS3D, which self-consistentlycombines 3D simulation of carrier transport, self-heating, and opt...

With the help of an electromagnetic field simulator (i.e., HFSS), the embedding impedance of a 660-GHz waveguide SIS mixer is thoroughly investigated using a lumped-gap-source and de -embedding method. The effects of the junction’s feed-point displacement and chip thickness are examined.

We designed and fabricated an electrically small antenna (ESA) with coplanar waveguide (CPW) matching circuit. Matching circuit is realized by using interdigital gap and transmission line. We designed ESA with the aid of the commercial three-dimensional electro magnetic field simulator. We also made experiments on the ESA with CPW matching circuits using patterned circuit board.

We observe dipole-like gap solitons in two-dimensional waveguide lattices optically induced with a self-defocusing nonlinearity. Under appropriate conditions, two mutually coherent input beams excited in neighboring lattice sites evolve into a self-trapped state, whose spatial power spectrum and stability depend strongly on the initial excitation conditions. Our experimental observations are co...

We analyze a family of singular Schrödinger operators describing a Neumann waveguide with a periodic array of singular traps of a δ′ type. We show that in the limit when perpendicular size of the guide tends to zero and the δ′ interactions are appropriately scaled, the first spectral gap is determined exclusively by geometric properties of the traps.

We experimentally study dispersive shock waves in nonlinear waveguide arrays. In contrast with gap solitons, the nonlinearity here pushes the propagation constant further into the transmission bands, facilitating Bloch mode coupling and energy transport. We directly observe this coupling, both within and between bands, by recording intensity in position space and power spectra in momentum space.

We theoretically demonstrate optical trapping using a silicon nitride (Si3N4) trench waveguide on which bow-tie plasmonic nanoantennas are employed for enhancing optical forces. The electric field tailing away from the waveguide is transformed and then enhanced by the plasmonic nanoantennas deposited on the waveguide surface. We show that, with gold bow-tie nanoantennas, the waveguide system ex...

The miniaturization of integrated optical circuits below the diffraction limit for high-speed manipulation of information is one of the cornerstones in plasmonics research. By coupling to surface plasmons supported on nanostructured metallic surfaces, light can be confined to the nanoscale, enabling the potential interface to electronic circuits. In particular, gap surface plasmons propagating ...
