OPTICAL FIBER WAVEGUIDE Optical Fiber Waveguides • An Optical Fiber is a dielectric waveguide that operates at optical frequencies • Normally cylindrical form • It confines electromagnetic energy in the form of light to within in its surfaces and guides the light in direction parallel to its axis Optical Fiber Waveguides core Cladding Buffer coatting Optical Fiber Waveguides • Refraction Exit ray Low index High index Partial internal reflection Incident ray Optical Fiber Waveguides • Critical angel Critical angel : Sin = n2/n1 Optical Fiber Waveguides • Total Internal Reflection Total internal reflection Optical Fiber Waveguides • Acceptance Angle
