$POETF $POET a further reminder of POET'S differentiation from the competition

POET’s Dielectric Interposer Differentiators taken from corporate presentation


Relative to Silicon Photonics
Ultra Low Loss Material - <0.5dB/cm loss demonstrated
Gain - SOA’s can be integrated for gain
Roadmap to Athermal Lasing - Enables tight wavelength spacings for future scaling
Low Loss Coupling - low coupling losses from laser to waveguides, low coupling losses to the fiber with fiber matched waveguide mode
External Modulators - electro-absorption modulators possible versus TW MZI
Directly Modulated Laser compatibility
WDM - Reach / Performance
Relative to Silica AWGs
Tighter Bend Radius - Substantially smaller Mux/De-Mux footprint
Enables LAN WDM wavelength spacing - Single chip quad channel lasers possible
InP Integration - capable of integration directly on InP, athermal gratings and filters on chip
Flexible mode matching capabilities - Multi waveguide structures possible for both chip side and fiber side mode matching, Variable and customizable refractive indices
Readily scalable to 12 inch Silicon Wafers
Low Stress - up to 20um Dielectric deposited with little to no stress
Manufacturable Mode Convertors

Waveguide Integration

Optical interposer
Dielectric waveguides on TOP of active or passive CMOS
No compromise in waveguide design versus CMOS design
Bulk silicon wafer promotes better laser thermal management
Interposers are largely passive wafers (high manufacturing yield)
Silicon Photonics
Si Waveguides in same layer as active CMOS
SOI thickness for CMOS not compatible with SOI thickness for transistors
Thermal management difficult – impacts laser reliability/cost
Silicon waveguides are lossy and not athermal
