PHYS 634 Photonics

Propagation of EM waves in Dielectric wave guide – Fiber optics (boundary conditions, phase and group velocity, attenuation and dispersion, cut off frequency, single and multimode fibers) – Emitters (LED &laser diodes DH, QW, BDR, DFB, VCSEL’s) - Fabrication techniques – Materials for photonics – Laser modulation (AM, FM and PM) and Demodulation – Receivers ( Detectors PIN, PMT, APD), homodyne and heterodyne detection – Sensors – Switching devices and wave guide switching.
