Ultralow Propagation Loss Slot-Waveguide in High Absorption Active Material

open access: yesIEEE Photonics Journal, 2014
A slot waveguide formed by high absorption active material is proposed to reduce the propagation loss for monolithic integration. The low propagation loss is attained by concentrating the optical field inside the low-index slot region without absorption.

Simulation demonstration and experimental fabrication of a multiple-slot waveguide

open access: yes, 2008
A multiple-slot waveguide is presented and demonstrated through theoretical simulation. Taking a double-slot waveguide as an example, the results show a nearly 30% enhancement of optical intensity compared with the traditional single-slot waveguide with ...

Waveguide slot antenna with a coupled dipole above the slot

open access: yesElectronics Letters, 1983
The effect of a parasitic dipole above a waveguide slot antenna is shown analytically and verified experimentally. The E-plane radiation pattern is shown to be rather sensitive to the change of dipole length, and an equalised E- and H-plane pattern is obtained by choosing a proper length of dipole.

Highly Efficient Phase-Matched Third Harmonic Generation From Mid-IR to Near-IR Regions Using an Asymmetric Plasmonic Slot Waveguide

open access: yesIEEE Photonics Journal, 2014
We theoretically propose an asymmetric plasmonic slot waveguide (APSW) with a thin silicon nanocrystal (Si-nc) layer and a thinner silicon layer that fills the bottom and the top of the metallic slot region to increase third-harmonic generation (THG ...

Enhanced four-wave mixing in graphene-integrated silicon slot waveguides

open access: yesApplied Physics Express
Leveraging graphene’s giant third-order nonlinearity and ultrafast response, we experimentally demonstrate a graphene-integrated slot waveguide designed to maximize the effective light–matter interaction. Through four-wave mixing experiments, we achieved

Comparative Study of Nano-Slot Silicon Waveguides Covered by Dye Doped and Undoped Polymer Cladding

open access: yesApplied Sciences, 2018
Nonlinear optical dyes doped in optical polymer matrices are widely used for electro-optical devices. Linear optical properties change with dye concentration, which leads to a change in modal properties, especially in nano-structured integrated ...
