Fiber Optic Communication - 1.5 Mode Theory

In this video we discuss on - Relationship between ray and wave - Ray theory -Small wavelength limit, advantages of ray theory - Relation between ray and mode - Modal concepts - Electric field distribution for various modes - Need for modal analysis - Modes in optical fiber - guided, radiation and leaky modes - Normalized frequency/ V number - Number of modes supported in fiber - Linearly polarized modes (LP) - SM fiber parameters - MFD, propagation modes - GI fiber - Refractive index, numerical aperture
