Comments about dispersion of light waves
Hervé C. Lefèvre
Dispersion of light waves is well known, but the subject deserves some comments. Certain classical equations do not fully respect causality; as an example, group velocity vg is usually given as the first derivative of the angular frequency ω with respect to the angular spatial frequency km (or wavenumber) in the medium

Generalized large optics fabrication multiplexing
Daewook Kim, Xiaolong Ke, Weslin Pullen, Tianyi Wang, Heejoo Choi, Vipender Singh Negi, Lei Huang, and Mourad Idir
High precision astronomical optics are manufactured through deterministic computer controlled optical surfacing processes, such as subaperture small tool polishing, magnetorheological finishing, bonnet tool polishing, and ion beam figuring. Due to the small tool size and the corresponding tool influence function, large

Atmospheric Plasma Jet processing for figure error correction of an optical element made from S-BSL7
Heike Müller, Thomas Waak, Uwe Birnbaum, Georg Böhm, and Thomas Arnold
To meet the increasing market demand for optical components, Plasma Jet Machining (PJM) of Borosilicate Crown Glass (BCG), which can be an alternative to Fused Silica, is presented. Surface figure error correction was performed by applying reactive plasma jet etching, where a fluorine-containing microwave driven plasma

It is a sufficient condition only, not a necessary and sufficient condition, for decomposing wavefront aberrations
Psang Lin
The classic equation for decomposing the wavefront aberrations of axis-symmetrical optical systems has the form,(1)W(h0,ρ,ϕ)=∑j=0∝∑p=0∝∑m=0∝C2j+m2p+mm(h0)2j+m(ρ)2p+m(cosϕ)mwhere j, p and m are non-negative integers, ρ and ϕ are the polar coordinates of the pupil, and h0 is the object height. However, one non-zero compo

Coherence onset in PT-symmetric organic microcavities: towards directional propagation of light
Karla Roszeitis, Markas Sudzius, Alexander Palatnik, Rebekka Koch, Jan Carl Budich, and Karl Leo
For the investigation of non-Hermitian effects and physics under parity-time (PT) symmetry, photonic systems are ideal model systems for both experimental and theoretical research. We investigate a fundamental building block of a potential photonic device, consisting of coupled organic microcavities. The coupled system

Optical characterization of strain sensing cables for Brillouin optical time domain analysis
Francesco Falcetelli, Filippo Bastianini, Pawel Bocheński, Leonardo Rossi, Raffaella Di Sante, and Gabriele Bolognini
Two innovative optical fiber cable layouts designed to improve strain measurement accuracy for Brillouin Optical Time Domain Analysis (BOTDA) sensors through improved strain transfer efficiency are presented and discussed. Swept Wavelength Interferometry (SWI) is used to experimentally evaluate their performance alongs
