Rouard's method as a modelling tool for the sensing characteristics of complex fibre Fabry-Perot interferometers formed between chirped fibre Bragg gratings [PDF]
, 2005 Phase and spectral response characteristics of fibre Fabry-Perot interferometers (FFPI), formed between linearly chirped fibre Bragg gratings (FBG), were theoretically modelled using Rouard's method.

Antenna surface plasmon emission by inelastic tunneling
Nature Communications, 2019 Developing a microscale ultrafast electrical source of surface plasmons is crucial for nanophotonic applications. Here, the authors report the design, fabrication and characterization of nanoantennas for emission and control of surface plasmons by ...

Polarization conversion with a photonic crystal slab [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 We show that a photonic crystal slab can enable efficient polarization conversion. Two mechanisms are identified. The first mechanism relies on the anisotropy of the bulk properties of the metamaterial and is mediated by interferences.

Role of Static Modes in Quasinormal Modes Expansions: When and How to Take Them into Account?
Mathematics, 2022 The scattering of electromagnetic waves by a resonator is determined by the excitation of the eigenmodes of the system. In the case of open resonators made of absorbing materials, the system is non-Hermitian, and the eigenmodes are quasinormal modes ...

Ultra-high-sensitivity two-dimensional bend sensor [PDF]
, 2006 A multicore fibre Fabry-Perot-based strain sensor interrogated with tandem interferometry for bend measurement is described. Curvature in two dimensions is obtained by measuring the difference in strain between three co-located low finesse Fabry-Perot ...

Design of nanofibres for efficient stimulated Raman scattering in the evanescent field [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 Nanofibres can be produced with diameters smaller than the wavelength of the light they guide. In this regime, the guided mode presents a strong evanescent field well adapted to the excitation of “evanescent nonlinearities”.

Experimental demonstration of a temporal pulse shaping method based on nonlinear chirp [PDF]
EPJ Web of ConferencesWe present a general temporal shaping method based on spectral phase-only modulation for ultrafast laser sources. We explain the working principle of this technique and use it experimentally to generate a ramp-shaped pulse at the output of a laser source

The American Mathematical Monthly, 2022 We present a short proof of the Fabry quotient theorem, which states that for a complex power series with unit radius of convergence, if the quotient of its consecutive coefficients tends to $ s $, then the point $ z=s $ is a singular point of the series. This proof only uses material from undergraduate university studies.
