Abstract

We present a tunable multi-channel optical true time delay (OTTD) using frequency interval tunable multiwavelength light source (MWLS). The frequency interval of MWLS can be flexibly tuned by programming a driving radio frequency (RF) signal. By using this tunable MWLS, the time delay difference (TDD) of multi-channel OTTD can be flexibly tuned with time in different function forms. The TDD of linear tuning with variation range of 61.84-119.71 ps and sinusoidal tuning with variation range of 60.97-87.76 ps with time are experimentally demonstrated.
