Picture of sea vessel plough through rough maritime conditions

Innovations in marine technology, pioneered through Open Access research...

Strathprints makes available scholarly Open Access content by researchers in the Department of Naval Architecture, Ocean & Marine Engineering based within the Faculty of Engineering.

Research here explores the potential of marine renewables, such as offshore wind, current and wave energy devices to promote the delivery of diverse energy sources. Expertise in offshore hydrodynamics in offshore structures also informs innovations within the oil and gas industries. But as a world-leading centre of marine technology, the Department is recognised as the leading authority in all areas related to maritime safety, such as resilience engineering, collision avoidance and risk-based ship design. Techniques to support sustainability vessel life cycle management is a key research focus.

A full description of the synthesis process for chirped and apodized integrated Bragg gratings is presented. Starting from a target complex reflectivity, the local Bragg and coupling coefficients are extracted and converted into physical grating parameters. Control over both the amplitude and group delay profiles of the devices may be exerted using a tapered sidewall relief grating design. Example devices, exhibiting bandwidths of up to 30 nm and both linear and quadratic group-delay profiles with up to a 13-ps span, are realized and compare well with their relative target functions. A passive measurement technique, employing a fully integrated Michelson interferometer, allows reconstruction of the fabricated gratings' amplitude and phase characteristics.
