Aims: To explain the fundamental principles of operation of optical devices.
Learning Outcomes: After completing the unit the student should have a clear understanding of: * optical waveguides; * the basic principles of operation of semiconductor optical devices; * the basic principles of Quantum Well materials and their applications in optoelectronics. Skills: Intellectual skills: basic maths, electromagnetic waves and semiconductor devices. Content: Introduction on optical communications systems and basic components. Optical waveguides modes. Optical gratings. Spontaneous, stimulated emission/absorption processes. Semiconductor lasers: principles of operation; Fabry-Perot resonator. Qualitative review of optoelectronic sources, e.g., LEDs, Superluminescent LEDs, designs for monochromatic sources (DFB/DBR lasers), VCSELs. Quantum Wells and their application in optoelectronics: simple introduction to Wave Mechanics, the "electron-in-a-box" problem, forming semiconductor quantum well and superlattices, quantum well lasers, Quantum Confined Stark Effect and electro-absorption modulators, electro-optic effects and their application to modulators and switches. Coupled mode theory. |
