Total Internal Reflection and Snell's Law - TikZ Figures¶
Fig: Optical fibre communication system: electrical input source driver optical source fibre channel photodetector receiver electronics recovered outputFig: Fibre cross-section: high-index core (n_1), lower-index cladding (n_2) and a protective coating/jacketFig: Rays entering within the acceptance angle _a undergo repeated total internal reflection and stay confined to the core; steeper rays refract into the cladding and are lost
