“…In another experiment, a high gain of more than 30 dB has been obtained in femtosecond regime by using the chirped-pulse amplification scheme [24]. In a continuous wave (CW) FOPA, large gain can be obtained in a bandwidth of 20 THz [25]. And a flat gain band over 16 nm has been reported by using dual-pump CW FOPA setup [26].…”

We report a fiber optical parametric amplifier (FOPA) based on a photonic crystal fiber (PCF) with optimized dispersion and nonlinear properties pumped by a mode-locked ytterbium-doped fiber laser. Wavelength-tunable parametric gain bands can be obtained by adjusting the pump wavelength from the anomalous to the normal dispersion regime. By utilizing the PCF-based FOPA, weak signals located in the parametric gain bands can be amplified. Wavelength-tunable picosecond pulses can be generated at the signal and idler wavelengths. A 58-dB maximum gain and a wide gain bandwidth from 999 to 1139 nm have been achieved by pumping near the zerodispersion wavelength. When the FOPA is pumped at 1062.5 nm in the normal dispersion regime of the PCF, the 974-nm weak continuous-wave signal is significantly amplified, and the idler pulse is generated at 1168 nm.

We demonstrate improved performance of parametric amplifier cascaded with Raman amplifier for gain of 54.79 dB. We report amplification of L-band using 100 × 10 Gbps Dense Wavelength Division Multiplexed (DWDM) system with 25 GHz channel spacing. The gain achieved is the highest reported so far with gain flatness of 3.38 dB without using any gain flattening technique. Hybrid modulated parametric pump is used for suppressing four-wave mixing (FWM) around pump region, resulting in improvement of gain flatness by 2.42 dB. The peak to peak variation of gain is achieved less than 1.6 dB. DWDM system with 16-channel, 25 GHz spaced system has been analyzed thoroughly with hybrid modulated parametric pump amplified Raman-FOPA amplifier for gain flatness and improved performance in terms of BER and -factor.

We present a flat, visible 1.3-octave supercontinuum generated in a GeO2-doped photonic crystal fiber owing to an overlap of the modulation instability and Raman gain regions resulting in efficient energy transfer to new frequency components.OCIS codes: (320.0320) Ultrafast optics; (320.6629) Supercontinuum generation; (060.2280) Fiber design and fabrication Supercontinua are of interest for numerous industrial applications including sensing, imaging, and frequency comb generation as well as in optical device characterization. Recently, Q-switched lasers were found to be compelling candidates for supercontinuum generation in the long-pulse regime [1][2][3]. Here we present supercontinuum generation between 620 -1552 nm in a highly doped photonic crystal fiber (PCF) pumped with a passively Q-switched sub-ns microchip laser at 1064nm. Efficient generation is enabled even at low pump powers owing to overlapping modulation instability (MI) and Raman gain regions.We designed a hexagonal lattice, solid-core silica matrix PCF with a 20% mol. GeO2 doped, m core and strong index contrast (n= 30x10 -3 ) between the core and the cladding (Fig.1a, inset) fabricated by PERFOS. The PCF has n2 = 4.709 x 10 -20 m 2 /W and a Raman gain of gR = 7.07x10 -14 m/W. We measured the zero dispersion wavelengths to be ZDW=1047 nm and 1050 nm for the two principal polarization axes. Dispersion is 6.44 ps/km-nm at 1064nm, the attenuation 0.17dB/m and =50 (W-km) -1 . In Fig.1a the supercontinuum is generated after 1m of fiber for various input powers: a flatness of <6 dB over 820 nm extending from 620 nm to 1440 nm (Fig. 1a), and <15 dB over 932 nm between 620 nm -1552 nm is observed for Pave=7.8mW (Ppeak=670W). This result is competitive with similar sources using longer fibers (1.8 -20 m) and higher peak powers [4][5][6] in the same ns pulse regime. Notably, in Fig. 1a we start seeing supercontinuum in 1m of fiber (bandwidth >250nm) at markedly low peak powers of 98W (Pave=1.1mW) with a 0.8ns, 14 kHz laser, lowest reported to our knowledge. The generating mechanisms of this supercontinuum are studied using the generalized nonlinear Schrodinger Equation (GNLSE) solver [7], modified to include measured attenuation and quantum noise. Simulation results (Fig. 1b) show an evolution starting from MI. Raman response of GeO2 reaches its maximum at 13.2THz extending from 10-15THz. Accordingly, MI and Raman peaks overlap, producing a highly efficient energy transfer from pump to shorter and longer wavelengths. This effect is primarily responsible for the extremely wideband spectrum competitive with current research-grade and commercial sources operating in the nanosecond pulse regime.
