A waveguide structured with a pitch smaller than the wavelength does not produce diffraction effects and instead behaves like homogenous metamaterial waveguide. The properties of this metamaterial can be lithographically controlled through the geometry of the subwavelength structure. In this webinar hosted by the OSA Optoelectronics Technical Group, Dr. Robert Halir from the University of Málaga will explore the physics that govern these structures and discuss strategies to efficiently model and simulate them. Dr. Halir will then discuss the design of a variety of high performance devices, ranging from low-loss fiber-to-chip couplers to ultra-broadband multimode interference couplers and highly sensitive biosensors, using sub-wavelength structures. We finish our discussion with considerations about the successful fabrication of these structures.

Who Should Attend:
Dr. Robert Halir, University of Málaga
Robert Halir received the MSc in Telecommunications Engineering with first-class honors from Málaga University (Spain) in 2006, and his PhD in the field of silicon photonics in 2010. Currently he is an assistant professor at Málaga University, as well as a researcher at the Andalusian Institute for Nano-medicine and Biotechnology (Bionand). Dr. Halir’s research focuses on high performance silicon photonic devices, including ultra-broadband couplers, highly efficient fiber-to-chip couplers and photonic biosensors. He made pioneering contributions to the field of silicon subwavelength structures and has authored comprehensive review papers on this topic. He has coauthored more than 60 papers in the field of integrated optics, holds several patents and regularly delivers invited talks at international conferences.
