Operando monitoring transition dynamics of responsive polymer using optofluidic microcavities
Light: Science & Applications, 2021 Operando monitoring transition dynamics of responsive polymer via a self-referencing optofluidic microcavity is demonstrated. The refractive index and temperature information of the analyte during the phase-transition process are precisely decoupled.

Electromagnetism with magnetic charge and two photons [PDF]
American Journal of Physics, 1996 The Dirac approach to include magnetic charge in Maxwell’s equations places the magnetic charge at the end of a string on which the the fields of the theory develop a singularity. In this paper an alternative formulation of classical electromagnetism with magnetic and electric charge is given by introducing a second pseudo-four-vector potential, Cμ, in

Experimental Investigation of Actively Q-Switched Er3+:ZBLAN Fiber Laser Operating at around 2.8 µm
Sensors, 2020 A diode-pumped Q-switched Er3+:ZBLAN double-clad, single-transverse mode fiber laser is practically realized. The Q-switched laser characteristics as a function of pump power, repetition rate, and fiber length are experimentally investigated. The results

Focusing Light with Curved Guided-Mode Resonance Reflectors
Micromachines, 2011 Employing numerical simulations, we investigate the possibility of using curved guided-mode resonance (GMR) elements to focus light in reflection. We treat GMR reflectors with a parabolic shape and show that they are capable of focusing light effectively

New electromagnetic memories and soft photon theorems [PDF]
Physical Review D, 2017 In this paper, we present a new type of electromagnetic memory. It is a `magnetic' type, or B mode, radiation memory effect. Rather than a residual velocity, we find a position displacement of a charged particle induced by the B mode radiation with memory. We find two types of electromagnetic displacement (ordinary and null). We also show that the null
