On-chip multi-stage optical delay based on cascaded Brillouin light storage

Stiller, Birgit; Merklein, Moritz; Wolff, Christian; Vu, Khu; Ma, Pan; Poulton, Christopher; Madden, Steve; Eggleton, Benjamin J.


Storing and delaying optical signals plays a crucial role in data centers, phased array antennas, communication, and future computing architectures. Here, we show a delay scheme based on cascaded Brillouin light storage that achieves multi-stage delay at arbitrary positions within a photonic integrated circuit. Importantly these multiple resonant transfers between the optical and acoustic domain are controlled solely via external optical control pulses, allowing cascading of the delay without...[Show more]
