摘要

Abstract

An in-line

all-optical fiber modulator based on a stereo graphene–microfiber structure (GMF) utilizing the lab-on-rod technique was demonstrated in this study. Owing to its unique spring-like geometry

an ultra-long GMF interaction can be achieved

and a modulation depth of ~7.5 dB (~2.5 dB) and a modulation efficiency of ~0.2 dB mW

−1

(~0.07 dB mW

−1

) were demonstrated for two polarization states. The modulation depth and modulation efficiency are more than one order of magnitude larger than those of other graphene–microfiber hybrid all-optical modulators

although at the cost of a higher insertion loss. By further optimizing the transferring and cleaning process

the upper limit of the modulation depth is mainly determined by the loss from the intrinsic absorption

which depends on the light–graphene interaction. Then

the modulator can quickly switch between the on-state and the off-state with a theoretically maximized modulation depth of tens of decibels. This modulator is compatible with the current fiber-optic communication systems and may be applied in the near future to meet the impending need for ultrafast optical signal processing.
