Does optical switch have another name?

  • #1
I need to know about optical switch for my optoelectronics course for physics majors. So far I only know its a switch which is controlled by light. I tried to search net but couldn't find any thing. Is optical switch have another name?

I'm trying to understand all optical switch from

http://www.phy.duke.edu/~qelectron/proj/switch/intro.php

in this page they mentioned,

As a first example, we illustrate the behavior of our switch, shown to the right. In this device, a single beam of light (blue) is emitted from a nonlinear material and exits in a certain direction. This is one of the two states of the switch; let's call it the "off" state. The switch is turned to the "on" state, when a second light beam, the switching beam (red), is injected into the nonlinear optical material. As a result, the output beam (blue) is emitted in a different direction.
I'm confused about nonlinear material and from where that blue light came? don't we need some kind of photon bombardment . . .

For example, in this paper the Kerr effect is used:

Most nonlinear effects are intensity dependent.

can't open the link :(

I'm an undergrad student - if optical switch suppose to be this difficult then it should be taught at graduate level.
