Bloch surface waves at the telecommunication wavelength with lithium niobate as the top layer for integrated optics
Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal
Lithium niobate (LN)-based devices are widely used in integrated and nonlinear optics. This material is robust and resistive to high temperatures, which makes the LN-based devices stable, but challenging to fabricate. In this work, we report on the design, ...
2019Spatial coherence properties of an LED-based illumination system for mask-aligner lithography
Hans Peter Herzig, Toralf Scharf, Wilfried Noell, Raoul Kirner, Johana Bernasconi
A high-power LED-based illumination system has been developed as a replacement for the mercury arc lamps used in mask-aligner lithography. LEDs are arranged in a grid array and placed in the entrance aperture of individual reflectors. Those reflectors decr ...
SPIE2019Magnetic spin–orbit interaction of light
Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal, Huihui Lü
We study the directional excitation of optical surface waves controlled by the magnetic field of light. We theoretically predict that a spinning magnetic dipole develops a tunable unidirectional coupling of light to transverse electric (TE) polarized Bloch ...
Nature Publishing Group2018Magnetic Spin-Orbit Interaction of Light Steers Bloch Surface Waves
Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal, Huihui Lü
We show the directional excitation of Bloch surface waves controlled by the magnetic field of light. The phenomenon in play is the first magnetic spin-orbit interaction of light. It opens new degrees of freedom in the manipulation of light and offers appea ...

IEEE2018High power modular LED-based illumination system for lithography applications
Hans Peter Herzig, Marcel Groccia, Toralf Scharf, Wilfried Noell, Raoul Kirner, Johana Bernasconi
Mask-aligner lithography is a technology used to transfer patterns with critical dimensions in the micrometer range from below 1 micron for contact printing to a dozen of microns in proximity printing. This technology is widely used in the fabrication of M ...
2018Lippmann waveguide spectrometer with enhanced throughput and bandwidth for space and commercial applications
Hans Peter Herzig, Mohammadreza Madi, Benedikt Guldimann, Philippe Giaccari
This article presents an innovative high spectral resolution waveguide spectrometer, from the concept to the prototype demonstration and the test results. The main goal is to build the smallest possible Fourier transform spectrometer (FTS) with state of th ...
2018Toward Bloch Surface Wave-Assisted Spectroscopy in the Mid-Infrared Region
Hans Peter Herzig, Grégoire Maxime Smolik, Nicolas Maxime André Descharmes
We present the first observation of Bloch surface waves in the mid-infrared spectral range. Bloch surface waves are electromagnetic states that can propagate at the interface between a continuous dielectric medium and a periodic stack of materials. We desi ...
2018Investigation of the Propagation Length of Bloch Surface Waves on One Dimensional Photonic Crystals, 2018 International Conference on Optical MEMS and Nanophotonics (OMN)
Hans Peter Herzig, Gaël David Osowiecki, Nicolas Maxime André Descharmes, Babak Vosoughi Lahijani
A 1D photonic crystal structure sustaining optical surface waves is investigated. The propagation length of the surface mode is studied both using an eigenmode model and a rigorous time domain solver. The two models show good convergence. Our results demon ...
2018Inverse photonic design of functional elements that focus Bloch surface waves
Hans Peter Herzig, Myun Sik Kim, Babak Vosoughi Lahijani, Andreas Vetter
Bloch surface waves (BSWs) are sustained at the interface of a suitably designed one-dimensional (1D) dielectric photonic crystal and an ambient material. The elements that control the propagation of BSWs are defined by a spatially structured device layer ...
