Figures & Tables(5)
Fig. 1. (a) Experimental setup. WDM, wavelength division multiplexer; LD, laser diode pump; CPS, cladding power stripper; MFA, mode field adapter; PCF, photonic crystal fiber; HNLF, highly nonlinear fiber; SC, supercontinuum. (b) Calculated dispersion curve. The inset shows the end face of the PCF. (c) Measured transmission loss of the PCF.
Fig. 2. (a) Spectral evolution of the 1/1.5 µm mixed pump with various output powers. (b) Output powers of the 1/1.5 µm radiations from the dual-band fiber amplifier. Output pulse trains at (c) 1 µm and (d) 1.5 µm at the maximum output power.
Fig. 3. Spectral evolution of the supercontinuum measured after (a) 1.4 m, (b) 5 m, and (c) 8 m PCF.
Fig. 4. (a) Output power of the generated supercontinuum measured after different lengths of HNLF as a function of the pump power. (b) Spectral evolution of the generated supercontinuum measured after 0.2 m HNLF.
