Low Loss Tapered Polysilicon Core Fibers [PDF]

Conference on Lasers and Electro-Optics, 2016
We have fabricated small core polysilicon waveguides by tapering bulk, as-drawn silicon optical fibers. The taper process acts to improve the local crystallinity of the core, resulting in a significant reduction in the material loss.

Low Loss Antiresonant Hollow Core Fibres [PDF]

Advanced Photonics, 2011
We study the loss mechanisms in novel antiresonant hollow-core fibres and demonstrate the importance of optimising the air-cladding thickness and reducing the node size. Based on these rules we fabricate fibres with wide-bandwidth and low-loss.
