Bloch Surface Based Platform for Optical Integration

Hans Peter Herzig, Elsie Barakat, Richa Dubey

A novel dielectric multilayer platform sustaining Bloch surface waves is investigated for integrated photonic chips. These surface waves can be manipulated by two dimensional dielectric optical components patterned on top of the platform. We study the prop ...

Optimal antibunching in passive photonic devices based on coupled nonlinear resonators

Vincenzo Savona

We propose the use of weakly nonlinear passive materials for prospective applications in integrated quantum photonics. It is shown that strong enhancement of native optical nonlinearities by electromagnetic field confinement in photonic crystal resonators ...

Multispectral Plasmon Induced Transparency in Coupled Meta-Atoms

Hatice Altug

We introduce an approach enabling construction of a scalable metamaterial media supporting multispectral plasmon induced transparency. The composite multilayered media consist of coupled meta-atoms with radiant and sub-radiant hybridized plasmonic modes in ...

Metallic Optical Nanostructures: a Solution for Planar Integrated Sensors on Waveguides

Hans Peter Herzig, Qing Tan, Armando Cosentino

We study the optical properties of two different metallic nanostructure arrays for lable-free sensing applications. The sensors are optimized to detect refractive index (RI) variations. The optical interaction between light and analyte is enhanced by field ...

The importance of the photonic mode density in bioassays based on evanescent optical waves

Akihiro Sato

We have determined limits of detection (LODs) of DNA hybridization using an optical detection by two different method, i.e., surface plasmon fluorescence spectroscopy (SPFS) and optical waveguide fluorescence spectroscopy (OWFS), however, an identical sens ...

The scale axis transform

Mark Pauly

We introduce the scale axis transform, a new skeletal shape representation for bounded open sets O ⊂ &Rdbl;d. The scale axis transform induces a family of skeletons that captures the important features of a shape in a scale-adaptive way and ...
