Subwavelength structures in integrated optics

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013
Subwavelenth structures offer exciting new opportunities for integrated optics. Effective refractive index can be chosen from a broad range by lithographic patterning using just two materials. Many practical subwavelength engineered devices already demonstrated, with superior performance compared to their conventional counterparts and likely many more ...

Enhanced Transmission from Visible to Terahertz in ZnTe Crystals with Scalable Subwavelength Structures.

ACS Applied Materials and Interfaces, 2021
The zinc blend nonlinear crystal of zinc telluride (ZnTe) is currently one of the most commonly used electro-optical material for terahertz (THz) probe and imaging.

Subwavelength waveguide structures for optical interconnects [PDF]

2015 17th International Conference on Transparent Optical Networks (ICTON), 2015
We report our advances in development of subwavelength engineered waveguide structures. This unique NRC patented technology [1,2] allows synthesis of a metamaterial with an unprecedented control of material properties, constituting a powerful tool for a designer of photonic integrated circuits.

Subwavelength structure imaging

Optical Engineering, 2004
We expand conventional superresolving imaging systems toward extraction of suboptical wavelength structures. An imaging system that is capable of imaging subwavelength details is presented. Homogeneous waves carrying information on spatial frequencies exceeding the classical limit of resolution can be created by diffraction of evanescent waves.

Subwavelength structures in SOI waveguides

8th IEEE International Conference on Group IV Photonics, 2011
Our progress in subwavelength structures in silicon waveguides is reviewed. Several practical implementations of subwavelength grating waveguides are discussed, including fibre-chip couplers, waveguide crossings and athermal waveguides.

Subwavelength structures for infrared filtering

SPIE Proceedings, 2010
This work deals with the replacement of the reflection layer stacks by sub-wavelength structures, which form the cavity of Fabry-Perot-Interferometer (FPI) infrared filters. Periodically arranged metal ring resonators are investigated regarding reflectivity and sensitivity with respect to polarization angle by Finite Difference Method (FDM) analysis.

Subwavelength-structured antireflective surfaces on glass

Thin Solid Films, 1999
Abstract The usability of porous sol–gel coatings and periodic or stochastic subwavelength surface-relief structures for low-cost broadband antireflective (AR) surfaces on glass and on plastics was studied experimentally. Porous sol–gel coatings were produced by dip-coating on glass.

Phase gratings with subwavelength structures

Journal of the Optical Society of America A, 1995
Polarization-selective gratings are designed by use of rigorous electromagnetic diffraction theory. The polarizing effects are attained by special surface-relief structures. We present a scheme for coding two different optical functions in one diffractive element.
