Generation of high power pulse of Bi-EDF and octave spanning supercontinuum using highly nonlinear fiber
A compact and stable system for the generation of a super-continuum (SC) at the 1550 nm region is proposed and demonstrated. Mode-locked pulses at a pulse-width of 200 fs and a peak power of 2.2 kW are generated using the nonlinear polarization rotation technique in a short length of Bi-EDF of about...

| Summary: | A compact and stable system for the generation of a super-continuum (SC) at the 1550 nm region is proposed and demonstrated. Mode-locked pulses at a pulse-width of 200 fs and a peak power of 2.2 kW are generated using the nonlinear polarization rotation technique in a short length of Bi-EDF of about 48.2 cm. The generated pulses at a repetition rate of 41.6 MHz are then launched directly into a 100 m long highly non-linear fiber, without requiring any amplification stages. The generated SC spectrum covers a range of 1200-1950 nm. The wavelength bandwidth of the SC is over 413.5 nm at the 3-dB power level and the SC pulse width is about 90 fs. |
