Strain‐Induced Optical and Molecular Transformations in Poly(Ethylene Terephthalate) Films for Organic Electronic Applications

open access: yesAdvanced Photonics Research, EarlyView.
This study explores how mechanical strain affects the optical and molecular properties of poly(ethylene terephthalate) (PET) films, crucial for flexible electronics. Using UV–Vis and Raman spectroscopy, it reveals strain‐induced changes in transparency and vibrational modes. Findings provide insights into optimizing PET‐based devices like organic solar

Design and Characterization of Low‐Threshold InP Nanowire Photonic Crystal Surface‐Emitting Lasers

open access: yesAdvanced Photonics Research, EarlyView.
The lasing performance of nanowire (NW) photonic crystal surface‐emitting lasers (PCSELs) is highly sensitive to changes in the photonic crystal lattice constant and the NW diameter. This study systematically investigates the threshold power and the threshold gain for different PCSEL geometries.
