Nanoimprint Fabrication of Slot Waveguides

IEEE Photonics Journal, 2013
A nanoimprint mold for optical waveguide applications was fabricated by combining photolithography and focused ion beam (FIB) milling. The feasibility of the proposed method was demonstrated by imprinting 15-mm-long Y-branch waveguides, which had ...

Numerical Investigations of Infrared Slot Waveguides for Gas Sensing

Proceedings, 2018
Sensing of gases is a promising area for applications of photonic sensor devices that operate in the mid-infrared spectral range. We present a numerical investigation of slot waveguides for evanescent field sensing of CO2.

Coupling Thermal Atomic Vapor to Slot Waveguides [PDF]

Physical Review X, 2018
We study the interaction of thermal rubidium atoms with the guided mode of slot waveguides integrated in a vapor cell. Slot waveguides provide strong confinement of the light field in an area that overlaps with the atomic vapor.

Opto-electrical characterization of erbium-doped slot waveguides [PDF]

, 2012
The convergence of photonics and microelectronics within a single chip is still lacking of a monolithical on-chip optical amplifier. Rare-earth doped slot waveguides show a large potential as on-chip source.

Mid‐Infrared on‐Chip Dichroic Filters Enabled by Adiabatic Evolution and Dispersion‐Engineered Subwavelength Grating Waveguides [PDF]

Nanophotonics
An on‐chip mid‐infrared dichroic filter is demonstrated using an asymmetric directional coupler theory comprising a longitudinally segmented subwavelength‐grating waveguide and a strip waveguide. Suppressed slot‐like scattering loss and precise dispersion engineering yield flat‐top responses over 3.3–3.7 μm, ∼0.9 dB insertion loss, ∼1 dB/nm roll‐off ...

Strong modulation instability in a silicon–organic hybrid slot waveguide [PDF]

, 2015
In this paper, we investigate the strong modulation instability (MI) at telecommunication band in a silicon-organic hybrid slot waveguide. The organic material of polymer poly (bis para-toluene sulfonate) of 2, 4-hexadiyne 1, 6 diol (PTS), which has high

Modeling of Slot Waveguide Sensors Based on Polymeric Materials

Sensors, 2011
Slot waveguides are very promising for optical sensing applications because of their peculiar spatial mode profile. In this paper we have carried out a detailed analysis of mode confinement properties in slot waveguides realized in very low refractive ...

Low-loss slot waveguides with silicon (111) surfaces realized using anisotropic wet etching

Frontiers in Materials, 2016
We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform. Waveguides oriented along the (11-2) direction on the Si (110) plane were first fabricated by a standard e-beam lithography and dry etching process.
