Ultra-compact silicon modulator with 110 GHz bandwidth

We demonstrate an ultra-compact silicon slow light modulator with a record-high EO bandwidth of 110 GHz, a modulation length of
$124\ \mu\mathrm{m}$
, an optical bandwidth of 8 nm around 1550 nm, and OOK transmission beyond 110 Gbps without DSP is achieved. © 2022 The Author(s)
