摘要： An optical regenerator for regenerating a multi-level phase encoded signal. A first non-linear medium (HNLF1) generates a comb of frequency harmonics from the signal under the action of a coherent pump, each component bearing the phase encoded data. A filter selects the first and (M−1)th order components. The filtered signal is then input to a second non-linear medium (HNLF2) where a further pump is applied, to coherently add the first and (M−1)th order components and regenerate the signal by reducing phase noise.

摘要： An optical passive repeater is provided. The repeater is operated under a state of polariton Bose-Einstein condensation (BEC). A phase transition from a thermal polariton state to a condensed polariton state is controlled, where system temperatures and densities are lower than thermal dissociation temperatures and nonlinear saturation densities, respectively. Original input multimode laser signals are transformed into final output single-mode laser signals. Thus, the polariton BEC passive repeater becomes a power-efficient and low-cost device to increase the reach of optical links without sacrificing its signal quality and integrity.
