We show the versatility of this simple but effective inscription method, where we demonstrate classic multiple slit diffraction patterns and show the potential for coarse wavelength division multiplexing for sensor signals. A key advantage for the fibre splitter is that the inscription method avoids the use of oil immersion that compensate for the fibre curvature in the standard side writing method. 2012 SPIE.||ISBN:||978-081949103-9||ISSN:||0277-786X (print)||DOI:||10.1117/12.968395||Rights:||@ 2012 SPIE||Type:||Conference Papers|
