Waveguide grating as a Bragg mirror on Bloch surface waves based platform for 2D integrated optics applications

Hans Peter Herzig, Richa Dubey, Babak Vosoughi Lahijani

We study and demonstrate a Bloch-surface-wave-based nano-thin waveguide grating. The waveguide grating is characterized as a Bragg mirror at telecommunication wavelengths. The structure is a dielectric multilayer platform designed to sustain a Bloch surfac ...

High Quality Factor Confinement Of Bloch Surface Waves At Visible Wavelengths

Raphaël Barbey, Hans Peter Herzig, Gaël David Osowiecki, Nicolas Maxime André Descharmes, Babak Vosoughi Lahijani

We report the first experimental demonstration of high quality factor confinement of Bloch surface waves at visible wavelengths. The cavities consist of planar Fabry-Perot resonators that are fabricated on top of a Bloch surface supporting substrate. This ...

Polarization controlled directional propagation of Bloch Surface Wave

Maria-Pilar Bernal, Hans Peter Herzig, Myun Sik Kim

Bloch surface waves (BSWs) are recently developing alternative to surface plasmon polaritons (SPPs). Due to dramatically enhanced propagation distance and strong field confinement these surface states can be successfully used in on-chip all-optical integra ...

Experimental evidence of Bloch surface waves on photonic crystals with thin-film LiNbO3 as a top layer

Maria-Pilar Bernal, Hans Peter Herzig, Myun Sik Kim

Strong nonlinear, electro-optical, and thermo-optical properties of lithium niobate (LN) have gained much attention. However, the implementation of LiNbO3 in real devices is not a trivial task due to difficulties in manufacturing and handling thin-film LN. ...

Phase-sensitive near field Investigation of Bloch surface wave propagation in curved waveguides

Hans Peter Herzig, Liang Sun, Qing Tan, Libo Yu, Elsie Barakat, Jian Wang

Bloch surface waves (BSWs) are electromagnetic surface waves excited in the band gap of a one dimensional dielectric photonic crystal. They are confined at the interface of two media. Due to the use of dielectric material, the losses are very low, which al ...

Guided Bloch Surface Waves on Ultrathin Polymeric Ridges

Tristan Sfez, Hans Peter Herzig, Olivier Martin, Daniele Brunazzo, Francesco Michelotti

We present a direct evidence of Bloch surface waves (BSWs) waveguiding on ultrathin polymeric ridges, supported by near-field measurements. It is demonstrated that near-infrared BSWs sustained by a silicon-based multilayer can be locally coupled and guided ...

Ultrathin waveguides for Bloch Surface Waves: near-field analysis of propagation and polarization

Tristan Sfez, Hans Peter Herzig, Olivier Martin, Daniele Brunazzo, Libo Yu

We demonstrate that an ultrathin ridge (< lambda/10) can guide Bloch surface waves in a dielectric multilayer. The propagation and polarization properties of the guided modes are investigated with a multi-heterodyne scanning near-field optical microscope. ...
