New H‐Shaped Conjugated Reactive Liquid Crystals with Exceptionally Low Birefringence for Advanced Polymer Optics

open access: yesAdvanced Optical Materials, EarlyView.
Herein, a novel class of conjugated H‐shaped liquid crystal molecules is developed with exceptionally low birefringence, designed for advanced optical applications. These reactive mesogens form transparent, well‐aligned polymer films and enable narrow‐band reflection in cholesteric systems.

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

open access: yesAdvanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...

Comparison of Glass Material and Laser Excitation Regime for Upconversion‐Based 3D Volumetric Display

open access: yesAdvanced Photonics Research, EarlyView.
This study explores scalable glass matrices for two‐step, two‐frequency (TSTF) upconversion‐based 3D volumetric displays. While Er3+‐doped TeO2–ZnO–Na2O (TZN) and BaO–Ga2O3–GeO2 (BGG) glasses show weaker TSTF upconversion than reference ZrF4–BaF2–LaF3–AlF3–NaF (ZBLAN) glass under continuous‐wave lasers, TZN surpasses ZBLAN under pulsed laser excitation
