Matrix Fourier optics enables a compact full-Stokes polarization camera
Recent developments have enabled the practical realization of optical elements in which the polarization of light may vary spatially. We present an extension of Fourier optics-matrix Fourier optics-for understanding these devices and apply it to the design ...
2019Stepwise Luneburg Lens for Bloch Surface Waves
Myun Sik Kim, Babak Vosoughi Lahijani
In order to enlarge the capability for in-plane manipulation of the Bloch surface wave (BSW), we investigate 2D gradient index (GRIN) optical components using a finite-difference time-domain (FDTD) numerical method. To ease difficulties in fabrication to a ...
2018Near-field characterization of Bloch surface waves based 2D optical components
Bloch surface waves (BSWs) are surface electromagnetic modes that propagate at the interface between a multilayer substrate and a homogeneous external medium. The optical field of the surface mode is confined near the surface of the multilayer. This vertic ...
EPFL2017Micro-structuring of glassy carbon for precision glass molding of binary diffractive optical elements
Hans Peter Herzig, Toralf Scharf, Karin Prater
Precision glass molding is a more cost efficient process for the large volume manufacturing of highly complex optical surfaces than direct manufacturing. Glassy carbon (GC) molds are used for precision glass molding, because they can be operated at tempera ...
Optical Society of America2016Two-dimensional polymer grating and prism on Bloch surface waves platform
Hans Peter Herzig, Elsie Barakat, Libo Yu, Joab Di Francesco
A one-dimensional photonic crystal sustaining Bloch Surface Waves (BSWs) is used as a platform for two-dimensional integrated optics. The dielectric platform shows low loss, long propagation distance and high surface field enhancement. In order to study th ...
Optical Society of America2015Towards new applications using capillary waveguides
Demetri Psaltis, Christophe Moser, Salma Farahi, Nicolino Stasio, Emmanuel André Henri Bossy
In this paper we demonstrate the enhancement of the sensing capabilities of glass capillaries. We exploit their properties as optical and acoustic waveguides to transform them potentially into high resolution minimally invasive endoscopic devices. We show ...
