At the Microdevices for Photonics Laboratory we study and develop advanced micro-optical devices for photonics with applications in biology, health, aerospace, and security.

Main topics are:

  • Whispering Gallery Mode Resonator (WGMR) based micro-optical devices for biosensing and for optoelectronic oscillators
  • WGMR based coherent and non linear sources
  • Supercontinuum Generation in non linear fibers for biological applications
  • Resonant gratings based photonic devices
  • Glass Integrated Optical waveguides
  • Nanotips for SNOM, AFM and biological applications
  • Fiber optical transmission lines for particles accelerators
