Fast electrical switching of orbital angular momentum modes on a silicon chip   
The BBOI teams from the Centre for Quantum Photonics of the University of Bristol and from the University of Glasgow have demonstrated an extremely compact optical vortex emitter with the ability to actively tune between different orbital angular momentum modes. On–off keying and orbital angular momentum mode switching are achieved at rates of 10 us and 20 us respectively.
The ability to rapidly switch between orbital angular momentum modes of light has important implications for future classical and quantum systems.

Controlling Photonic Circuits,
Noninvasively     
The drive to squeeze thousands of photonic elements into smaller and smaller integrated circuits, and to aggregate multiple components on a single chip, is creating an ever-greater need to monitor, control, and fine-tune those circuits in real time.
But how can one harvest information about the optical signal in these circuits without tapping the light itself, and thereby sapping the device’s optical power?
A research team from Italy and Scotland has proposed a new approach to cracking that problem, and providing noninvasive monitoring and feedback control, for one important class of photonic device, silicon photonic microresonators...

BBOI results published in Optica

26 August 2014        
BBOI has demonstrated non-invasive monitoring and control in silicon photonics using CMOS integrated electronics. 
This results has been published in Optica, the new high-impact journal of the Optical Society of America (OSA).

In this work, high-quality-factor silicon photonic resonators are monitored by the transparent CLIPP detector technology developed by BBOI.
Control operations are entirely managed by a CMOS microelectronic circuit that is bridged to the Si photonic chip and hosts many parallel electronic readout channels. Advanced functionalities, such as wavelength tuning, locking, labeling, and swapping, are demonstrated.

Bridging EU projects: BBOI meets PARADIGM


31 July 2014
     
Two apparently different European projects that exchange ideas, share facilities and mutually exploit their results.
It is not a story we can read very often, but when it happens it is a great success, not only for the involved partners but for the whole EU funding scheme. And this is the case of BBOI and PARADIGM.
