OptoelectronicsLaajuus (5 ECTS)

Objective

Students are familiar with optical communication methods and have theoretical understanding of it. Students are familiar with optical transmitters and receivers and they have basic understaning of optical link system operations.Students know technically how to create optical signal from electrical signal and vice versa. Students are familiar with the guiding and routing of optical signals in waveguide systems. Students are familiar with the transmitter and receiver diode structure properties which effect the wavelength sensitivity range.- Fabry-Perot principle and thin film layer structure in dielectric mirror reflections.

- Optical signal in wave guide channel; attennuation, dispersion, scattering, and optical link resource calculation methods.
- LED- , ELED- ja SLED- diode structures.
- Optical amplifier operation.
- VCSEL, lightamplifier and PIN- diodi operation parameters.
- Light conductors
