Abstract

Abstract In this paper, we propose the use of a coaxial fiber as a suitable first order dispersive medium to achieve pulse repetition rate multiplication by use of the temporal Talbot effect. A design optimization of the coaxial fiber is discussed to achieve first order dispersion over a desired bandwidth. Pulse repetition rate multiplication is demonstrated by simulating the propagation of a Gaussian pulse train through the coaxial fiber using analytical expressions. The results are compared with those obtained in an ideal first order dispersive medium and by use of the conventional single mode fiber.
