Title Proper : DYNAMIC PROPERTIES OF QUANTUM DOT DISTRIBUTED FEEDBACK LASERS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Semiconductor quantum dots (QDs) are nano-structures with three-dimensionalspatial confinement of electrons and holes, representing the ultimate case of theapplication of the size quantization concept to semiconductor hetero-structures. Theknowledge about the dynamic properties of QD semiconductor diode lasers is essential toimprove the device performance and understand the physics of the QDsIn this dissertation, the dynamic properties of QD distributed feedback lasers(DFBs) are studied. The response function of QD DFBs under external modulation ischaracterized and the gain compression with photon density is identified to be thelimiting factor of the modulation bandwidth. The enhancement of the gain compressionby the gain saturation with the carrier density in QDs is analyzed for the first time withsuggestions to improve the high speed performance of the devices by increasing the-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
