Open Access research that is better understanding work in the global economy...

Strathprints makes available scholarly Open Access content by researchers in the Department of Work, Employment & Organisation based within Strathclyde Business School.

Better understanding the nature of work and labour within the globalised political economy is a focus of the 'Work, Labour & Globalisation Research Group'. This involves researching the effects of new forms of labour, its transnational character and the gendered aspects of contemporary migration. A Scottish perspective is provided by the Scottish Centre for Employment Research (SCER). But the research specialisms of the Department of Work, Employment & Organisation go beyond this to also include front-line service work, leadership, the implications of new technologies at work, regulation of employment relations and workplace innovation.

Abstract

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.
