Abstract
Graphene oxide (GO)-doped SU-8 waveguides have been fabricated and characterized. The GO-doped SU-8 can be processed using standard photolithography parameters. The optical characteristics of the developed waveguides are determined using fibre-butt coupling and cut-back method. Propagation loss of 1.9 dB/cm and a coupling loss of 4 dB per point measured at 1550 nm wavelength are obtained. Q-switched laser operation is achieved by inserting a 3 mm GO-doped SU-8 waveguide into a ring fibre laser configuration, making it a potential candidate as integrated saturable absorber for on-chip polymer waveguide applications.
