Narrow bandwidth optimization using a polymer microring resonator in a thulium–holmium fiber laser cavity

Abstract

A thulium-holmium fiber (THDF) laser cavity has been demonstrated with a SU-polymer microring resonator (PMRR) in the cavity. The PMRR has a μm radius and fabricated using the lithography method, with the SUpolymer acting as a host material. The butt coupling method was used for the horizontal coupling of light from a ▻ Authors ▻ Keywords Brought to you by INTERNATIONAL ISLAMIC UNIVERSITY MALAYSIA Search Sources Lists ↗ SciVal Create account Sign in References (20) Engineering controlled terms: Bandwidth Fiber lasers Fibers Holmium Laser resonators Numerical methods Resonators Spectrum analyzers Thulium Engineering uncontrolled terms Free spectral range Holmium fibers Laser oscillators Narrow bandwidth Polymer microring resonators Polymer waveguides Radio frequency spectrum Ultra-high numerical apertures Engineering main heading: Polymers Funding details Funding sponsor Funding number Acronym
