Literary linguistics: Open Access research in English language

Strathprints makes available Open Access scholarly outputs by English Studies at Strathclyde. Particular research specialisms include literary linguistics, the study of literary texts using techniques drawn from linguistics and cognitive science.

The team also demonstrates research expertise in Renaissance studies, researching Renaissance literature, the history of ideas and language and cultural history. English hosts the Centre for Literature, Culture & Place which explores literature and its relationships with geography, space, landscape, travel, architecture, and the environment.

Abstract

Polarization switching (PS) in 1550-nm VCSELs under single and double pulsed polarized optical injection is investigated experimentally and in theory. “Normal” and “reverse” PS were achieved, respectively, when the device was subject to single and double optical injection. Speed operation enhancement is observed for “reverse” PS under double polarized optical injection. Also, the minimum injection power requirements for both “normal” and “reverse” PS have been analyzed showing significant differences for the two investigated cases. Furthermore, we have also investigated numerically the influence of important system parameters, such as the normalized bias current, the injection field strength, and the linewidth enhancement factor in the optimal operation conditions for both types of PS. Overall good agreement between theory and experiments is found.
