Abstract :
We present noise and distortion measurements of multicast copies generated in a self-seeded parametric mixer. Linear mixer operation is achieved by distortion-free Brillouin suppression resulting in high signal-to-noise and distortion-ratio (SINAD) wavelength copies. SINAD of 48 dB was measured after the multicasting operation, corresponding to a digitized signal having more than 7.7 effective number of bits (ENOB). This represents the most linear and noiseless parametric mixer reported to date.
