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.

“Photonics”


Why light for communications

Optical communication

High carrier frequency (1014 Hz)

Low carrier frequency

(Almost) no modulation effects

Distortion of modulated signals

Dielectric waveguides

Conducting waveguides

Low loss

Frequency dependent loss

Small wavelength

Large wavelength

Tight confinement

Why light for communications ?

Electrical transmission lines


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*

Limitations of electrical interconnects: the off-chip challenge
