After this course the student:
- understands the propagation of electromagnetic fields: propagation constant, wavelength, refractive index, electromagnetic field as a superposition of monochromatic waves of different frequencies (temporal FT), electromagnetic field as superposition of waves with different spatial frequencies (spatial FT).
- knows the Maxwell equations and their relation with Schrödinger equations: solution to the Maxwell equations, boundary conditions, wave equation.
- has a general notion of the dispersion relation (ω-k), its meaning, and relation to the E-k diagrams of electrons in solids (neff vs meff). Application to optical waveguides.
- has a general notion of the principles of photodetection, light emission and lasing in semiconductors.
- understands the working principle of a laser.
- understands the rate equations for photons and carriers in a semiconductor laser, threshold current, slope efficiency, photon lifetime.
- knows the concepts direct modulation of a semiconductor laser, frequency chirp, maximum modulation speed.
- knows the modulation schemes, including on-chip optical modulators.
