摘要

We experimentally demonstrate a novel expansion architecture for a gain-switched laser, based on simultaneous injection-locking of multiple modes of a gain-switched Fabry-Perot laser, using a dual-stage active demultiplexer. A 6.25 GHz expanded comb with a spectral bandwidth over 875 GHz (expansion factor similar to 10) is presented. (C) 2022 The Author(s)
