Abstract

We present and demonstrate an all-fiber scheme of polarization temporal differentiation (PTD) based on polarization coupling and filtering, which performs well in high-speed optical differentiation, pulse multiplication, and femtosecond-pulse reshaping. Experimental results of the first-order differentiation show the error is 0.1 with an efficiency of 12% for optical signals at 40Gbits/s, while both error and efficiency are proportional to the square of the time delay, which agrees well with the theoretical analysis. By PTD-based two-stage pulse multiplication of a 20GHz optical clock, we obtain an 80GHz picosecond-pulse train with a full width at half maximum of 6.1ps. We further reveal its potential in femtosecond-pulse reshaping, while we retrieve a distorted 250fs original pulse by using a two-stage PTD module. Because of its flexible structure, multifunctionality, and easy integration, the PTD scheme is desirable for photonic signal processing.
