Photonics
  • The PHOTON is to PHOTONics as the ELECTRON is to
    ELECTRONics.
  • Three major developments in the recent past are
    responsible for the rejuvenation of this field
  • Invention of the diode laser (1961)
  • Fabrication of low loss fiber (1970)
  • Maturing of semiconductor optical devices (1970s
    to present)
  • Modern definition of photonics as applied to
    communications generation, modulation,
    transmission, and detection of light.

3
Why light for communications ?
  • Optical communication

Electrical transmission lines
4
Limitations of electrical interconnects the
off-chip challenge
  • As data rates increase, electrical interconnects
    are limited by
  • Power
  • Distortion
  • Cross-talk
  • Pin-out capacity
  • Fundamental Aspect ratio limit
