Electric and magnetic optical nano-antennas for probing and controlling the electromagnetic optical near-fields.
Institut FEMTO-ST in Besancon, France
Recently, resonant nano-antennas have been proposed for establishing a two-way communication channel between optical nano-structures and free space radiations, thus enhancing light-matter interaction down to the nanoscale. We present here our recent advances in the development of a single electric nano-antenna at the extremity of an optical fiber for the near-field imaging and remote control of photonic crystal microlasers. We will also introduce a nano-antenna aimed at enhancing and confining the magnetic optical field.
Thierry Grosjean received his PhD degree in 2003 from the University of Franche-Comté in near-field optical microscopy and related techniques. He obtained a postdoctoral position at the University of Muenster, in Germany (Humboldt fellow) to work in plasmonics and optical nanofocusing. He joined the CNRS in 2005 as a permanent researcher to work in the field of nanophotonics. His main scientific interest addresses the development of optical nano-antennas.
