2. What is silicon photonics?
Silicon is a chemical element that is widely used as a semiconductor
Photonics is the science and technology of light
A photon is a quantum of light energy

3. Silicon-based Lasers
Will allow information to travel by light in gigabytes per second
Could be made with same equipment used for microprocessors

4. How the laser works Silicon and indium phosphide are bonded together
Electric current is sent through the combination
Negative and positive particles combine with the indium phosphide and produce photons
The photons produce a beam of light

5. Silicon Modulator
A modulator is a device that processes various periodic waveforms to use that signal to transmit a message
Can encode data at 30 gigabits/second
Possible to make faster computers that produce less heat

6. How the modulator works
It contains a diode that allows electric current to flow in only one direction
Light goes through it at one end and splits into two beams that go through silicon diodes
The diodes alter the position of the light wave
This alteration encodes data which represents a 1 or 0

7. Benefits to businesses
Transactions and information at the speed of light
Better decisions because of more information
Smaller devices improve commerce
Cheaper costs and higher profit margin
