Inverse 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 ...

High-power modular LED-based illumination systems for mask-aligner lithography

Hans Peter Herzig, Toralf Scharf, Johana Bernasconi

Mask-aligner lithography is traditionally performed using mercury arc lamps with wavelengths ranging from 250 nm to 600 nm with intensity peaks at the i, g and h lines. Since mercury arc lamps present several disadvantages, it is of interest to replace the ...

Hybrid surface wave device

Hans Peter Herzig, Myun Sik Kim

We present a hybrid surface wave device, which combines Bloch surface wave (BSW) and plasmonic nanoantennas. BSWs offer in-plane dark-field illumination. Nanoantennas squeeze the incidence into nano-size and enable far-field readout without near-field tech ...

Investigation of the Propagation Length of Bloch Surface Waves on One Dimensional Photonic Crystals

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 ...

Manipulation of Bloch surface waves: from subwavelength focusing to nondiffracting beam

Hans Peter Herzig, Myun Sik Kim

We present a different type of electromagnetic surface wave than a surface plasmon polariton (SPP), called Bloch surface wave (BSW). BSWs are sustained by dielectric multilayers, and therefore they do not suffer from dissipation. Their propagation length i ...
