Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes
Advanced Optical Materials, EarlyView.This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.

The Algorithm for Solving Quantum Linear Systems of Equations With Coherent Superposition and Its Extended Applications [PDF]
arXivMany quantum algorithms for attacking symmetric cryptography involve the rank problem of quantum linear equations. In this paper, we first propose two quantum algorithms for solving quantum linear systems of equations with coherent superposition and construct their specific quantum circuits.

Advanced Photonics Research, EarlyView.Ultrafast pulsed laser technology enables precise material processing. This study examines molybdenum oxide formation under varying laser parameters. A dataset of 187 samples is generated, and eight deep neural networks (DNNs) with different architectures are trained. Models are validated using three learning rates and evaluated with mean squared error,

Advanced Photonics Research, EarlyView.Multiple incoherent nonlinear deconvolutions (MIND) has extended dimension for optimization that provides a better solution than Wiener deconvolution and nonlinear reconstruction. MIND minimizes deconvolution noise by averaging over multiple deconvolutions each with different system aperture that effectively enhances the resolution.

Understanding the Temperature Conditions for Controlled Splicing Between Silica and Fluoride Fibers
Advanced Photonics Research, EarlyView.Thermal splicing conditions are investigated between silica and ZrF4 fibers, focusing on mechanical strength. A fiber Bragg grating characterises the thermal profile in the filament splicer's hot zone. Results indicate a narrow temperature window for strong joints.

Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber
Advanced Photonics Research, EarlyView.Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for

Charge generation in organic solar cells: Journey toward 20% power conversion efficiency
Aggregate, Volume 3, Issue 6, December 2022., 2022 Herein, a photophysicist's views on charge generation in organic solar cells is discussed. Recent steady‐state and time‐resolved spectroscopic studies regarding the exciton diffusion to donor:acceptor interfaces, charge transfer at the donor:acceptor interface, and long‐range spatial dissociation of charge transfer states are highlighted.
