Ultra flat supercontinuum generation in silicate dual core microstructured fiber

Abstract

Abstract:In this paper we report on ultra flat supercontinuum generation in dual core photonic crystal fiber pumped in the normal dispersion regime. The fiber cladding is fabricated from custom NC21 borosilicate glass while the fiber cores is made of commercially available F2 high index lead-silicate glass from Schott Corp. We investigated the supercontinuum characteristics for single and double core excitation by a Ti:Sapphire oscillator delivering 100 fs pulses centered at 800 nm with an energy of 4.2 nJ. Dual core pumping resulted in appreciable flattening of the supercontinuum spectra in the range 875 -950 nm.Wavelength λ, nm λ Intensity I, dBm

Supercontinuum generation up to 2.5 μm in photonic crystal fiber made of lead-bismuth-galate glass

“…However PCFs based on soft glasses have also been used successfully for broadband supercontinuum generation [2,4]. A lot of attention has been focused on the various parameters that define the quality and the application area of the supercontinuum namely, power density, time dependence, pump regime, flatness, and bandwidth of spectrum.…”

Nd-doped phosphate glass microstructured optical fiber laser

“…Microstructured optical fiber (MOF), also known as photonic crystal fiber (PCF) [14], has created new applications in a large number of diverse areas of research and technology, such as ultra flat 1 The article is published in the original. supercontinuum generation [15], linearly polarized short length fiber lasers [16] and versatile optical device [17,18]. Recently, A single mode, single fre quency fiber oscillator had been demonstrated in a short length Er/Yb co doped phosphate glass PCF [7].…”
