Motivation
Features:
DIRECTIONLESS: Change the
configurartion of Add/Drop wavelength
channels to/from any direction
COLORLESS: Independence from
transponder wavelength
CONTENTIONLESS: Multiple signals
with the same wavelength can be handled
by the same device
Nodes in Metro networks
Objective: integrated transponder aggregator

IRIS TPA characteristics• 48 optical channels, with 100 GHz spacing in the C-
band, 4 different directions and 12 add/drop channels
• Density of photonic components (>1k on <30 mm2 chip area) controlled by >2k electronic building blocks.
• lower cost (a few hundred Euro) and overall device volume a factor of 60 smaller (only a few cubic centimetres)

• Silicon photonics is a mature technology
• Silicon photonics has already moved from laboratories to applications
and markets
• Quantum technologies can take benefit from dense integration,
scalabiity, roboustness and low losses of Silicon Photonics circuits
• Integrated quantum circuits has already reached a high level of
complexity (> 100 components)
• Integrated quantum silicon photonics is now moving to the market
