Supercontinuum generation in photonic crystal fiber using femtosecond pulses
Supercontinuum (SC) generation in photonic crystal fiber (PCF) is demonstrated using an amplified femtosecond stretched pulses. The stretched pulse is obtained from a mode-locked Erbium-doped fiber laser and operates at 1564 nm with a repetition rate of 8.27 MHz and a pulse width of 340 fs. Using a...

| Summary: | Supercontinuum (SC) generation in photonic crystal fiber (PCF) is demonstrated using an amplified femtosecond stretched pulses. The stretched pulse is obtained from a mode-locked Erbium-doped fiber laser and operates at 1564 nm with a repetition rate of 8.27 MHz and a pulse width of 340 fs. Using a 50 m long PCF, broad SC spectra are observed starting from 1220 and 1050 nm for the corresponding 5.1 and 177 kW pump and spanning a wavelength region of more than 1750 nm. At a maximum peak pump power of 177 kW, flat SC which extends over bandwidths of 660 and 486 nm are obtained using 50 and 100 m piece of PCF respectively. However, the output power level is higher for the 100 m PCF especially at longer wavelength region. |
