Paper Abstract

A direct UV written single-mode planar Bragg grating element is demonstrated, with >300 GHz of applied strain tuning. The degree of tuning that the fabricated device has leads to a potential application in dynamic optical networks as an optical add-drop multiplexer. The filter bandwidth is 23±5 GHz and can be tuned over a 308-GHz range by applying transverse strain across the device's composite silica-on-silicon structure.
