The major topics addressed include the derivation and explanation of governing equations that model the closely coupled physics processes in optoelectronic devices; numerical solution techniques for the governing equations arising from the first section, and how these techniques are jointly applied in device simulation; and real-world design and simulation examples of optoelectronic devices, such as Fabry-Perot and distributed feedback laser diodes, electro-absorption modulators, semiconductor optical amplifiers, superluminescent light emitting diodes, and their monolithic integrations.
Target application of the Near Field Holography (NFH) process is within the optical industry especially in the telecom industry, where the need for integrated optical circuits such as distributed feedback (DFB) lasers and other grating-based integrated components is growing rapidly.
