Interference based microwave photonic bandpass filters (MPBF) form an important component of modern RF signal processing. The presence of multiple optical components in an RF photonic system e.g. fiber amplifiers, waveguides, cause a degradation in t

We report the characterization of continuous-wave four-wave mixing (FWM) in SM1950 and SMF-28 silica fibers in the 2 μm wavelength band. Maximum conversion efficiencies of -21 dB and -25 dB are achived for SM1950 and SMF-28 fibers, respectively. In
