Okay, lets make this clear.
A sensor consists of a camera behind a lens and a light source.
The thing that is glowing - is the light source. It has nothing to do with the sensor or anything. It's there so that the camera "sees" the surface of the mousepad.
If you want, you can change that diod to a blue one, or an infared one and the mouse will still work, with, perhaps, lower specs.
The thing that actually is responsible for the movement of the mouse cursor - is the little lens that has nothing visible emitting from it. Its placed near the LED, but in reality can be placed anywhere, just as long as there is sufficient light.
So no, the sensor doesnt get the information from the light source. It gets it from the lens. The lightsource is only there to give sufficient light for the camera to capture differences in the surface
