We want to design an optical surgery system to deliver an intense beam of near-UV light (3.2eV energy) within the body. Assume that we want to generate this light using a semiconductor laser. We have several potential options for materials for the active layer, the cladding, and the substrate. find several potential options for active layer materials. Determine the appropriate composition for each of the options that will give the desired behavior. Then, select an appropriate cladding materials for each of the active layer options.
To deliver the light, we use an optical fiber. If the fiber is at most 2m long, and we want 99% of the power to be transmitted, what is the maximum attenuation a that the fiber could have?
