Optical injection in semiconductor lasers for RF signal generation

Speaker:  Dr. Antonio Hurtado (University of New Mexico)

Date: Friday, October 4, 2013
Time: 2 PM - 3 PM
Location: Whittemore 654 (6th Floor Conference Room)

Abstract:

In this talk we review the research carried out at the Universities of Essex (UK) and New Mexico (UNM) analyzing optical injection in different laser structures, including vertical-cavity surface emitting lasers and quantum dot distributed feedback lasers. Special emphasis will be given to analyzing the potentials of optically-injected semiconductor lasers for the development of compact, tunable and low cost microwave, millimeter and THz signal generators.

Speaker:

Dr. Antonio Hurtado received the PhD degree in Telecommunication Engineering from the Universidad Politécnica de Madrid (Spain) in 2006. Since 2007 he has been with the Optoelectronics Research Group of the University of Essex (UK) first as a Post-Doctoral Fellow and then as a Marie Curie Fellow, after being awarded with a Marie Curie Fellowship (Intra-European Fellowships Programme, 2007) by the European Commission. In 2010 he was awarded with a second Marie Curie Fellowship (International Outgoing Fellowships Programme) to carry out a collaborative project between the Universities of Essex and New Mexico (UNM). Following this award in 2011 he started working at the UNM’s Center for High Technology Materials.

His research focuses in Semiconductor Lasers, including Vertical-Cavity Surface Emitting Lasers (VCSELs) and Nanostructure Lasers (such as Quantum-Dot or Quantum-Dash). He is interested in the effects of Optical Injection in Semiconductor Lasers including Bistability, Nonlinear Switching, Injection Locking, Nonlinear Dynamics, etc. His present research work concentrates on the analysis of optically-injected nanostructure semiconductor lasers for ultra-high frequency applications and also for neuronal dynamics emulation for novel concepts in computing. He has published over 100 papers in international scientific journals and conferences.
