TL;DR: Owing to the very small footprint of the delay line, a fully integrated device is feasible, also featuring more complex and elaborate filter functions, and both notch and band-pass microwave filters that can be tuned over the 0-50-GHz spectral band are demonstrated.

TL;DR: A new architecture for active coherent beam combining of a large number of fibers using a self-referenced quadriwave shearing interferometer and active control with arrays of electro-optic ceramic modulators is demonstrated.

TL;DR: The generated true time delay is analyzed as a promising solution to feed phased array antenna for radar systems and to develop dynamically reconfigurable microwave photonic filters.

TL;DR: The demonstration of an integrated frequency modulated continuous wave LiDAR on a silicon platform where the waveform calibration, the scanning system, and the balanced detectors are implemented on a chip is presented.

TL;DR: This technique appears suitable for the combination of a large number of fiber amplifiers, and the residual phase error between two fibers is as low as λ/90 RMS, while a combining efficiency of ∼50% is achieved.
