Optoelectronic Communication Technology
This is a one-semester lecture for students of the International M.Sc. Course
It provides a solid basis for understanding fiber-optic data transmission systems. Components of the system like fiber transmission media, light emitting diode or laser diode transmitters as well as photodiode receivers are discussed in some detail. From the component properties, bit rate transmission characteristics of the system are derived.
The following topics are addressed:
The lecture is a prerequisite to the Optoelectronics Laboratory Course.
- Properties of optical communication systems
- Optical fibers: ray-optical model, step-index and graded-index fibers, wave-optical model, chromatic dispersion
- Wave propagation in planar waveguides
- Loss in optical fibers: absorption and scattering
- Fabrication of fibers
- Semiconductor materials: crystal lattices, direct and indirect bandgaps, mixed compound semiconductors, absorption and refractive index, emission and absorption
- Light emitting diodes
- Laser diodes
- Optical communication systems: detection sensitivity for digital signals, optical power budgeting
- Optical fiber amplifier
