Since the discovery of the Bragg's law in 1913, Bragg gratings have become important
optical devices and have been extensively used in various systems. In particular, the …

As light cannot be stopped or directly stored in any media, optical delay lines are usually
used to temporally trap the optical signals. We report a wide-range continuously tunable …

We design, fabricate, and characterize a 7-bit reconfigurable optical true time delay line
consisting of Mach-Zehnder interferometer (MZI) switches on the silicon photonics platform …
