Abstract

We demonstrate both passive and active mode-locking of fiber lasers using a graphene-based absorber integrated on a silicon photonics platform manufactured using a wafer-scale CMOS process. Passive mode-locking is achieved at a 28 MHz repetition rate, generating 1.7 ps optical pulses, while active mode-locking is demonstrated at repetition rates of 4 GHz and 10 GHz. This work demonstrates the potential of scalable graphene-based saturable absorbers for fiber laser locking and paves the way for future fully integrated mode-locked laser systems.

摘要

我们展示了基于石墨烯的吸收体集成在采用晶圆级CMOS工艺制造的硅光子学平台上实现光纤激光器的被动和主动锁模。被动锁模在28MHz重复频率下实现，产生1.7ps光脉冲，而主动锁模在4GHz和10GHz重复频率下得到演示。这项工作展示了可扩展的基于石墨烯的饱和吸收体用于光纤激光器锁模的潜力，并为未来的全集成锁模激光系统铺平了道路。
