<p>This thesis presents the methods to extract modal parameters of semiconductor laser diodes based on a general zero-dimensional rate equation model. Three experiments, namely: the steady-state power versus injection current, small signal intensity modulation response and measurement of small signal response through dispersive optical fiber have been introduced, performed and analyzed under a sample space of 20 Multiple Quantum Well (MQW) Distributed feedback (DFB) laser of the same specification and from the same manufacturer. Testing software has been developed to perform the experiments , collect and analyze the data. The test results display an interesting Gaussian distributions that can be used to enhance further extraction process.</p> <p>An new method to extract the line-width enhancement factor has been purposed, which introduce a new way to extract rate equation parameters for laser lasing at the wave length for zero dispersion in optical fiber (1310nm). The new method circumvent the difficulty for measurement of small signal response through dispersive optical fiber method will not work due to the low fiber dispersion around this wavelength. This method has been validated and published at OSA conference.</p> / Master of Applied Science (MASc)
