摘要: Abstract E-beam field writing strategies have been developed to reduce stitching errors nigligible levels. Applying these strategies, 40mm × 4mm grating structures written onto phase masks which in turn used print gratings into photo-sensitive fibres. Transmission measurements from constant pitch with uniform and single shifts as well chirped are reported.
