MANIPULATING BEAMS OF LIGHT
Using optical elements
• Lenses
• Mirrors
• Polarizers
• Shutters
• Spatial filters
• Wavelength filters
• Phase plates
• SLM
Does not scale very well

PHOTONIC CHIPS
Chips for manipulating light
• fabricated on semiconductor wafers
• generating, modulating, filtering, detecting of
light
• Application in communications, sensing,…

PHOTONIC CHIPS
Complexity of the circuits depends on
• number of functional blocks
• density of integration
Circuits connect elements together
with waveguides
Laser
Modulator
Wavelengthfilter
Fiber Coupler
Photodetector
Fiber Coupler

SILICON PHOTONIC CHIP AND CIRCUIT SCALING
Khanna et al. 2016
Rapidly growing integration
• O(1000) components on a chip
• photonics + electronic drivers
• different applications (mostly comms)
• Relatively small chip volumes
(compared to electronics)
number of components/chip
