Wide-angle spectral imaging using a Fabry-Pérot interferometer [PDF]
Journal of the European Optical Society-Rapid Publications, 2015 We show that wide-angle spectral imaging can be achieved with compact and cost-effective devices using Fabry-Pérot interferometers. Designs with a full field of view of 90°, in which the Fabry-Pérot interferometer is mounted either in front of an imaging

Anticaustics in a Fabry–Perot interferometer
Journal of the Optical Society of America A, 2022 We address the response of a Fabry–Perot interferometer to a monochromatic point source. We calculate the anticaustics (that is, the virtual wavefronts of null path difference) resulting from the successive internal reflections occurring in the system.

Micromachined Fabry-Perot optical filters [PDF]
ASDAM '98. Conference Proceedings. Second International Conference on Advanced Semiconductor Devices and Microsystems (Cat. No.98EX172), 2002 The design, fabrication and measured characteristics of micromachined Fabry-Perot (F-P) optical filters for the visible spectral range are presented. Silver films of 40-50 nm thickness, evaporated on a 300 nm thick low-stress silicon nitride membrane, are used as high-quality mirrors.

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.
