Picosecond All-Optical Logic Gates (XOR, OR, NOT, and AND) in a Fiber Optical Parametric Amplifier

Abstract

We demonstrate all-optical XOR, OR, NOT, and AND gates in a fiber optical parametric amplifier within the same experimental setup. Error-free operation was achieved for 10Gb/s RZ signals with pulsewidth suitable for 100Gb/s operation.

All-Optical Logic Gates: Designs, Classification, and Comparison

“…When only one of the signals is present and launched into the HNL-DSF, it appears at the output, but if both the signals are present, no significant power appears at the output due to the state of polarization between the given data. By coupling these two output signals, one can achieve the desired results depending on the strength of the XGM [7,8]. In the design (Figure 2(c)), all-optical logic gates are realized on the nonlinear polarization rotation (NPR) in HNLF.…”

Investigation for achievable NCG of optical FEC coding with convolutional code using optical XOR gates based on four‐wave mixing in highly non‐linear fibre

“…The optical signal processing can overcome the trade-off between operational speed and power consumption to directly perform the required operation, avoiding any opt-electro conversions. In particular, various technologies have been studied including label recognition [1,2], bit pattern generator [3,4], logic gate [5,6], half and full adder [7,8], encryption [9], and forward error correction (FEC) [10][11][12][13]. Among these components, optical FEC technology is considered to be the most versatile for the communication system.…”

Reconfigurable and simultaneous implementation of all-optical logic gate using four-wave mixing (FWM) in HNLF for NRZ-olSK signal

“…Reconfigurable logic gates are highly preferred as they can provide a more flexible set of network functions. Several implementations of reconfigurable logic gates using semiconductor optical amplifier (SOA) 1,2 and highly nonlinear fiber (HNLF) [3][4][5] have been proposed. SOA-based schemes have limited operation rate (hardly exceed 40Gb/s) due to the slow carrier recovery time.…”
