Fibre Optic Communication : Key Devices The book gives an in depth description of key devices of current and next generation fibre optic communication networks. Devices treated include semiconductor lasers optical amplifiers modulators wavelength filters and other passives detectors all optical switches but relevant properties of optical fibres and network aspects are included as well. The presentations include the physical principles underlying the various devices technologies used for their realization typical performance characteristics and limitations but development trends towards more advanced components are also illustrated. This new edition of a successful book was expanded and updated extensively. The new edition covers among others lasers for optical communication optical switches hybrid integration monolithic integration and silicon photonics. The main focus is on Indium phosphide based structures but silicon photonics is included as well. The book covers relevant principles state of the art implementations status of current research as well as expected future components Optical Networks Optical Fibre Lasers Ultrafast Lasers Widely Tunable Lasers Photodetectors High Order Modulation Formats Modulators Wavelength Filters Optical Switches Passives Connectors Optical Circulators Optical Isolators Fibre Amplifiers SOAs Hybrid Integration (Silica Triplex Silicon Polymer Monolithic Integration on InP Basis Silicon Photonics Sources Silicon Photonics Monolithic Integration
