A photonic microwave true-time delay utilizing an asymmetrically tapered chirped fiber Bragg grating whose cladding is partially side-polished is proposed and demonstrated. A resistive heating electrode is incorporated on top of the tapered fiber in order to control the time delay continuously witho
## Abstract Differential group delay (DGD) generation by inducing birefringence in uniform fiber Bragg gratings (FBG) is studied. Applying a transverse load, a birefringence is induced on a uniform FBG creating a tunable differential group delay. A theoretical behavior of this phenomenon is present
