Abstract

We demonstrate phase-sensitive amplification of multiple wavelength-division-multiplexed continuous-wave (CW) signals by frequency nondegenerate four-wave-mixing process in optical fiber. By fine-tuning the optical wavelengths of the CW signals, simultaneous phase-sensitive in-line amplification of three signal channels is realized. This indicates the possibility of amplifying multiple data channels by an in-line phase-sensitive fiber parametric amplifier. We also discuss a potential system architecture employing such amplifiers.

Experimental setup for in-line phase-sensitive amplification of multiple CW-signal channels. HNLF—highly nonlinear fiber, FBG—fiber Bragg grating, PD—photo detector, AWG—array wave guide, FPC—fiber polarization controller, OBF—optical bandpass filter, PZT—piezoelectric transducer.

Phase-locked gain of the in-line PSA. Diamonds—phase-locked PSA gain, squares—corresponding PIA gain, circles—difference between the PSA and PIA gains.

Left: asynchronous phase-sensitive amplification of three CW channels; from top to bottom the red, blue, and purple traces represent the outputs of channel 3, channel 2, and channel 1 at wavelengths of 1553.97 nm, 1551.88 nm, and 1550.23 nm, respectively. Right: synchronous phase-sensitive amplification of three CW channels; from top to bottom the red, blue, and purple traces represent the outputs of channel 3, channel 2, and channel 1 at wavelengths of 1554.18 nm, 1551.88 nm, and 1550.08 nm, respectively. Triangular waves at the bottom of both movies show the voltage waveform driving the PZT, as a time reference (horizontal scale is 10 ms/div). [Media 1][Media 2]

Optical spectrum of light at the in-line PSA output. Black trace: PSA output with the pump turned off. Blue trace: PSA output with the pump turned on and phase-locking achieved. Three signal channels are at wavelengths of 1554.18nm, 1551.88nm, and 1550.08 nm.

Optical transmission system architecture enabled by the frequency nondegenerate PSA with input signal-idler preparation via a PIA. The dashed-line shaded box shows a single PSA node with add/drop capability. PLL: phase-locked loop, WDM: WDM coupler.
