An all-optical modulator based on a stereo graphene–microfiber structure Open
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…

Polarization-dependent all-optical modulator with ultra-high modulation depth based on a stereo graphene-microfiber structure Open
We report an in-line polarization-dependent all-optical fiber modulator based on a stereo graphene-microfiber structure (GMF) by utilizing the lab-on-rod technique. Owing to the unique spring-like geometry, an ultra-long GMF interaction le…

The influence of van der Waals forces on the waveguide deformation and power limit of nanoscale optomechanical systems Open
The ultra-short range force, van der Waals force (VWF), will rise rapidly when one nanoscale waveguide is close to another one, and be stronger than the external transverse gradient force (TGF). We theoretically investigate the giant influ…
