This is a graduate level course on Photonics (with a focus on lasers) and light-matter interaction in nanostructures. Manufacturing processes including lithography are also part of this course.
Notes will keep updating as the course proceeds.
Topics
- Transfer Matrix formalism for ray optics: Refraction by curved surfaces
- Jones Matrix for polarization: Conversion to right circularly polarized light,Wolfram computation
- Gaussian beams : Power conversion factor for Amplitude of gaussian beam, spot size
- Blackbody radiation, Planck’s Law
- Spontaneous and Stimulated Emission : Einstein coeffs and lifetime relations for atomic spontaneous and stimulated radiation
