BBOI results in Advanced Optical Materials

12 January 2017  
Lithium-ion intercalation enables reconfigurable metasurfaces
The BBOI teams from University of Munster and Politecnico di Milano have demonstrated the possibility to realize tunable metasurfaces by exploiting intercalation of lithium ions.

Tuning the phase and amplitude response of achiral and chiral metasurfaces is a key operation in optical science and technology, since it lies at the heart of devices like wavefront shapers, beam steerers, and many others. The concept of ion intercalation is bridged from the domain of electrochemistry to that of photonics, paving the way for a new class of reconfigurable optical devices.

BBOI gets ultra-high-performance quantum photonics

10 January 2017

Ultra-high-performance quantum photonics 
The BBOI team at the University of Bristol has demonstrated ultra-high fidelity single-qubit operations on chip, by using additional optical degrees of freedom, showing bright light extinction ratios as high as 60 dB.

Separately, the team has shown ultra-high-extinction filters—capable of separating a bright laser beam from on-chip single photons. Future on-chip quantum photonics will rely on both advances to achieve the required performance.

BBOI research awarded at GTTI meeting

17 June 2016
PhD student Andrea Annoni, from Politecnico di Milano, has won the “Best Junior Carassa Award 2016”.
The Ph.D. student competition was held during the 2016 Meeting of the GTTI association (Gruppo Telecomunicazioni e Tecnologie dell’Informazione).

The awarded research titled “MIMO Photonic Integrated Unscrambler for Mode Division Multiplexing” was realized thanks to a collaboration between the Photonic Devices Group and the I3N group (Innovative Integrated Instrumentation for the Nanoscience) of Politecnico di Milano.
