Light transistor: Efficient transistor for light could lead to optical computers

[unable to retrieve full-text content]Light can oscillate in different directions, as we can see in the 3-D cinema: Each lens of the glasses only allows light of a particular oscillation direction to pass through. However, changing the polarization direction of light without a large part of it being lost is difficult. Scientists have now managed this feat, using a type of light ? terahertz radiation ? that is of particular technological importance.
