Fiber Optic Lab
In this activity you will construct a simple light guide using water and a length of vinyl tubing. The water and vinyl tubing will act as the core, while air will act as the cladding or boundary layer. The experiment will demonstrate how effective even a simple light guide is for coupling energy from a light source to a detector. You will also observe how the light guide can carry light “around a corner” with relatively little loss compared to when light travels in a straight line.
Works good, lots of loss, tomorrow we will use real fiber
