Fiber cavity ring down and gain amplification effect
Silva, Susana; Magalhães, Regina; Pérez Herrera, Rosa Ana ; López-Amo Sáinz, Manuel ; Marques, M. B.; Frazão, Orlando (Springer Nature, 2016)
Artículo / Artikulua
The effect of an erbium-doped fiber amplifier (EDFA) placed inside the fiber ring of a cavity ring down (CRD) configuration is studied. The limitations and advantages of this configuration are discussed, and the study of ... -
Generation of lossy mode resonances with different nanocoatings deposited on coverslips
Fuentes Lorenzo, Omar; Goicoechea Fernández, Javier ; Corres Sanz, Jesús María ; Del Villar, Ignacio ; Ozcariz Celaya, Aritz ; Matías Maestro, Ignacio (Optical Society of America, 2020)
Artículo / Artikulua
The generation of lossy mode resonances (LMRs) with a setup based on lateral incidence of light in coverslips is a simple platform that can be used for sensing. Here the versatility of this platform is proved by studying ... -
Improving the width of lossy mode resonances in a reflection configuration D-shaped fiber by nanocoating laser ablation
Fuentes Lorenzo, Omar; Vaiano, Patrizio; Del Villar, Ignacio ; Corres Sanz, Jesús María ; Matías Maestro, Ignacio (Optical Society of America, 2020)
Artículo / Artikulua
The full width at half maximum (FWHM) of lossy mode resonances (LMRs) in the optical spectrum depends on the homogeneity of the thin film deposited. In this Letter, a method for improving the FWHM is applied for an LMR ... -
Photonic crystal fibers for sensing applications
