Embodiment 1

[0029] as attached figure 1 As mentioned above, the pulse to be compared with a repetition rate of 10 GHz and a wavelength of 1554 nm is used as the control signal, and continuous light with a wavelength of 1550 nm is used as the detection signal. The average power of the control signal needs to reach hundreds of milliwatts; the average power of the detection signal reaches ten milliwatts. Watts or so. The first Sagnac ring based on the cross-phase modulation effect, as shown in the attached figure 2 As shown, the pulse to be compared is input from terminal A as a control signal, enters the wavelength division multiplexer 3 through the polarization controller 1 outside the ring, and propagates clockwise in the ring. The continuous light as the detection signal is input from the B terminal through the optical circulator 2-1 to the 3dB coupler 6 and divided into two paths, one path clockwise passes through the wavelength division multiplexer 3, and enters the non-linear coeffi...

Abstract

Provided is an all-optical comparator based on serial self phase modulation effect. The all-optical comparator is composed of a Sagnac ring based on cross phase modulation and five consecutive Sagnac rings based on the self phase modulation. The five Sagnac rings based on the self phase modulation all adopt non-geometric couplers. According to the all-optical comparator, the non-geometric couplers and corresponding high nonlinear optical fibers are adopted, the complexity of the structure is reduced, and the all-optical comparator is suitable for high-speed light signal processing.

Description

technical field [0001] The invention relates to an all-optical comparator device, in particular to an all-optical comparator device based on the effect of serial self-phase modulation, which is suitable for the field of high-speed optical signal processing. Background technique [0002] Digital systems not only have obvious advantages over analog systems in terms of anti-interference ability and transmission accuracy, but also facilitate large-scale integration and encryption processing. While the digital system has achieved rapid development in recent years, as a key component of the interface between the analog and digital systems, the analog-to-digital converter has attracted more and more attention. [0003] Analog-to-digital converters in the electrical field are limited by the accuracy of external electrical clocks and the physical limit of carrier mobility, making it difficult to obtain conversion rates and accuracy that match contemporary communication systems. All-...
