Paper Abstract

A simultaneous generation of multiwavelength optical picosecond pulse trains is demonstrated by the use of multiple-optical-path self-seeding scheme. The external cavity of the Fabry-Perot laser diode consists of three fiber Bragg gratings (FBGs) and a variable optical delay line. The wavelengths of the optical short pulses can be selected conveniently by adjusting the fiber Bragg grating and can be switched simply by just adjusting the optical delay line. The side mode suppression ratio better than 18dB has been achieved when using a 1:99 optical coupler to enhance the seeding power, but the pulse train should be amplified for practical use. The system is simple, easy to operate and of low cost.
