What is inside this report, what is not
• In this report, Yole is investigating primarily active silicon photonic devices:
– Lasers, detectors, VOAs, optical switches other active elements that have an electrical or electronic control of
the optics. Active devices and elements generate light, detect light or actively change the direction, intensity,
color or polarization of light signals.
• Not included are passive devices that may be based on silicon and glass.
– These include silica-on-silicon, Silicon dioxide (SiO2) or other technologies.
– Examples of these devices are Array Wave Guides (AWGs), optical filters, couplers, splitters, polarizers, taps,
combiners, optical connectors, Planar Light Circuits (PLC) etc.
– Most of these devices are simply coatings on glass or silicon and are passive devices that have been built for
many years.
• Passive Silicon photonics - However, these devices mentioned can be built using silicon photonics
fabrication technologies and sold as individual devices.
– We include these in “passive silicon photonics” and in active silicon photonics as elements when integrated.
• Not included: Solar cells, silicon photo detectors, sensors (fiber or temperature, pressure, audio, etc.),
coated glass windows, general optics, lenses, mirrors, etc..
• Main focus is on Si photonics but we also describe integrated photonics trends.
