Abstract

A 1.0µm-band supercontinuum (SC) with a flat spectral bandwidth of 6.0nm is generated using a seed pulse source consisting of a CW light source, a phase modulator and a dispersion medium. And we use a photonic crystal fiber (PCF) as the nonlinear medium. PCF can be designed to realize high nonlinearity and low dispersion in the 1.0µm band. Moreover, we showed that we could fine-tune the optical spectrum of the SC by changing the modulation index Δθ of the phase modulator in the seed pulse source. We also describe the application of the supercontinuum as a multi-wavelength pulse source in the 1.0µm band.
