Flexible and tensile microporous polymer fibers for wavelength-tunable random lasing
preprint
posted on 2023-11-30, 20:34 authored by Van Duong Ta, Dhruv Saxena, Soraya Caixeiro, Riccardo SapienzaFlexible and tensile wavelength-tunable micrometer-sized random lasers in the form of microporous polymer fiber are demonstrated. The fibers are fabricated by directly drawing from an aqueous mixture and subsequently selective chemical etching in a green solvent. Size-dependent lasing threshold and spectrum are investigated. Owing to mechanical flexibility, wavelength-tuning of 5.5 nm is achieved by stretching the fiber.
