Photonic Waveguide Devices Directly Written into Dielectric Materials Using Femtosecond Laser Pulses

Abstract

In this paper we will present our most recent contributions to the fleld of femtosec- ond laser direct written waveguides. In particular, at the CUDOS at Macquarie we employed novel femtosecond laser beam delivery techniques in order to fabricate low-loss photonic waveg- uide devices for application in technologies such as telecommunications. After trialling various passive devices including waveguides, 1-N splitters and waveguide-Bragg gratings in non-doped glasses, we transferred our technologies into Erbium/Ytterbium co-doped media resulting in ac- tive Photonic devices.
