Semester IV
PH4CMT02: OPTICS AND SOLID STATE PHYSICS
Module I
Interference, Diffraction and Polarization (22 hours)
Light waves- phase difference and coherence, optical path and phase change, principle
of superposition, Analytical treatment of interference-- young’s double slit experiment,
conditions for interference, bandwidth Interference in thin films-reflected system-colour of
thin films-fringes of equal inclination and equal thickness. Newton’s rings-reflected
system-measurement of wavelength
Fresnel and Fraunhofer diffractions.Fresnel’s theory of approximate rectilinear
propagation of light. Fraunhofer diffraction.Theory of Plane transmission grating-
determination of wavelength- dispersive power of grating. Prism and grating spectra,
resolving power, Rayleigh criterion, resolving power of grating,
Polarization, types of polarization, Brewster’s law, dichroism, birefringence – e ray and o-
ray, polarizer and analyzer, Malu’s law, optical activity
Module II
Laser and Fiber Optics (10 hours)
Principle of operation of laser-population inversion, metastable states, optical resonator-
components of laser- active medium, pump, optical resonant cavity- principal pumping
schemes- three level and four level- laser beam characteristics, applications of lasers.
Light propagation in optical fibers, acceptance angle, numerical aperture-step index fiber
- graded index fiber.
Module III

Dielectrics- polar and non-polar dielectrics- polarization- sources of polarization-Gauss’s
law in dielectrics- permittivity- dielectric displacement vector- dielectric constant-
susceptibility- ferro-electricity.
