Three different types of hollow core, fibers are used for the fabrication of the devices and at two different wavelengths. An oscillatory-decreasing transmitted optical power is obtained as the thickness of the nanofilms is increased.3 p.application/pdfeng© 2006 Society of Photo-Optical Instrumentation EngineersHollow core fibersOptical fiber devicesNanofilmsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccessAcceso abierto / Sarbide irekia
