It is significant to improve the bandwidth of supercontinuum (SC) and the spectral flatness by more than one wavelength pumping. The broadband spectrum generation by induced phase modulation (IPM) in optical fiber was investigated by Yamashita et al. [1]. Schreiber et al. investigated the SC generation in PCFs by femtosecond single and dual wavelength pumping [2]. In this work, we investigate the...
Supercontinuum generation (SCG) in an all-normal dispersion fiber possesses a high degree of coherence, which has several applications. Traditional air-hole photonic crystal fibers have some limitations for achieving such light emission. In this paper, hybrid fibers with a silica glass cladding and a yttria–alumino–silicate glass core, designed for flat coherent SCG, were fabricated. The core material...
