Abstract

We have demonstrated for the first time to our knowledge, the conversion of 10 Gb/s non-return-to-zero (NRZ) on-off keying (NRZ-OOK) to RZ-OOK using cross-phase modulation (XPM) in a compact, Silicon (Si) nanowire and a detuned filter. The pulse format conversion resulted in a polarity-preserved, correctly-coded RZ-OOK signal, with no evidence of an error-floor for BER < 10−11. The advantages of a passive Si nanowire can lead to a compact, power-efficient, highly simplified configuration, amenable to chip-level integration.

Experimental set-up used to convert 10 Gb/s NRZ-OOK to RZ-OOK: PPG = pulsed-pattern generator, PRBS = Pseudo-random bit sequence, ODL = optical delay line, HPE = high-power EDFA, OBPF = optical band-pass filter, FBG = fiber Bragg grating, VOA = variable optical attenuator (Δα = differential attenuation), PRX = receiver power, LNF = low-noise figure, CR = clock recovery, TIA = transimpedance amplifier, and ED = error detector.

(a) 10 Gb/s pump trace (acquired using a 40 GHz detector, into a 50 GHz sampling module), and (b) 10 Gb/s NRZ-OOK probe (acquired using a OC-192 opto-electronic sampling module). The ripples in the zero rail in (a) are due to ringing in the combined response of the detector and the sampling module, as well as pattern-dependence due to the 40 Gb/s EOM. The time axis was set to 20 ps / division for both traces.

Spectra of the composite signal for various scenarios (resolution bandwidth (RB) of optical spectrum analyzer (OSA): 0.1Å). The probe is located at ~1540 nm, while the pump, at 1553.5 nm. The traces have been offset relative to each other for clarity.

(a) Converted RZ-OOK signal, and (b) Signal rejected by circulator. Signals were captured using a OC-192 opto-electronic sampling module. The ringing in the zero rail in (a) is due to sampling module response. The OSNR was ~40 dB / 0.1 nm RB for both signals. The time axis was set to 20 ps / division for both traces.

Spectra of the probe at various conditions. The residual probe carrier in the converted signal is circled in red. The streak extending from the black trace is an OSA sweep artifact. The spectra have been offset relative to each other for clarity.
