ABSTRACT
In this paper, we demonstrate fabrication and characterization of Ge-doped flat fibres. The Ge-doped flat fibre was fabricated from a 6 mol% Ge-doped preform. The flat fibre was successfully fabricated using dual stage drawing. Near field characterization was done and results show similar modal profile patterns as simulated using the software COMSOL. The results confirmed that with dual stage drawing and optimized drawing parameters, flat fibres with no defect holes can be fabricated.
