Abstract

Integrated electro-optic frequency combs are important components for future applications in optical communications, and these often require an efficient modulation mechanism. The authors demonstrate power-efficient lithium niobite phase modulators for electro-optic comb generation by implementing a 4x multi-pass configuration via mode multiplexing allowing for an experimental 15x reduction in power consumption; they demonstrate a broadband comb spectrum with 47 lines at 25-GHz comb spacing. © The Author(s) 2023
