Abstract

A scheme of multiwavelength picosecond pulses generator using time lens by cascading Intensity Modulator (IM), Phase Modulator (PM) and Single-Mode Fiber (SMF) is proposed and experimentally demonstrated. In the experiment, single wavelength pulse with Full Width at Half-Maximum (FWHM) of about 14ps at 5.2GHz are obtained, four wavelength interleaved pulse trains with time intervals between adjacent wavelengths is about 48ps at 20.8GHZ and eight wavelength interleaved pulse trains with time intervals between adjacent wavelengths is about 24ps at 41.6GHz are obtained by using Tunable Delay Line (TDL) and a Variable Optical Attenuator (VOA) combined Dense Wavelength Division Multi-plexing (DWDM). This scheme has flexibility and tunability because the repetition rate, and time-interval can be readily controlled.
