We investigate the temporal dynamics of truncated Airy pulses (TAPs) propagating in optical waveguides governed by the Chen-Lee-Liu equation (CLLE), focusing on the interplay between the CLL nonlinearity, truncation, and initial chirp. Weak...

We derive closed-form analytical sensitivities of pseudophakic refraction with respect to corneal power (K), axial length (L), effective lens position (E), and intraocular (IOL) power (P) from a single implicit paraxial vergence equation. E...

We present a method for detecting indirect, off-axis light radiated by a laser beam propagating in the atmosphere, in the presence of (primarily solar) background. Unlike in most existent methods, where laser light detection is based on its...
Low-sampling-rate compressed ghost edge imaging via energy-descending ordered speckle patterns [0.03%]

Yuqiao Zeng et al.
Computational ghost imaging (CGI) for edge detection, particularly speckle-shifting ghost imaging (SSGI), faces a severe trade-off between sampling cost and edge quality. We propose energy-descending ordered compressed ghost edge imaging (E...
Automated design of a Galilean array system for compact wide-angle solar concentration using the fourth-order Runge-Kutta method [0.03%]

High-quality optical cavities are widely used in sensing due to their exceptional sensitivity. However, most commercial systems rely on narrow-linewidth tunable lasers and active frequency tracking, increasing the system cost and complexity...
Singularities of optical currents, competition of local orbital angular momenta in astigmatic Gaussian beams, and experiment [0.03%]
光学电流的奇点、非对称高斯光束中局域轨道角动量的竞争以及实验研究

As a rule, transitions between the optical current singularities in vortex beams with a general astigmatism are associated with changes in featured orbital angular momentum (OAM) states (zeros and extremes). However, we have brought to ligh...
Parallel string comparison using spatially separated controlled-SWAP gates based on Laguerre-Gaussian modes of light [0.03%]

Color matching functions (CMFs) play important roles in color specification, characterization, and reproduction. Though the CIE 1931 2° CMFs are widely used in practice, its well-known weaknesses and poor performance have motivated great e...
