Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems

Laser &Photonics Reviews, EarlyView.
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...
