Direct growth of a graphitic nano-layer on optical fibers for ultra-fast laser application

Abstract

Direct growth of graphitic nano-layer (GNL) on optical fiber is achieved using plasma-enhanced chemical vapor deposition. Clean and uniform GNL nanocrystalline flakes are grown in a controllable manner on the fiber-end without catalysts. 991 fs soliton pulse generation at 1559 nm is achieved using the GNL coated optical fiber in an erbium-doped fiber laser.
