1. 1. Generation and Transmission of Optical Solitons at Ultrahigh Bit Rates

   Författare :Bamdad Bakhshi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear optics; chirp-free optical pulses; lowpass filtering; polarization-maintaining fibers; optical communication; optical solitons; Erbium fiber ring laser; dispersion-management; active mode-locking; soliton interactions; erbium-doped fiber amplifier; Gaussian pulses;

   Sammanfattning : This thesis deals with the generation and transmission of optical solitons in ultrahigh-speed fiber-optic communication systems. For optical soliton pulses the fiber dispersion and nonlinearity can under certain circumstances cancel each other, thus allowing the solitons to remain undistorted over long distances. LÄS MER

3. 2. High Power, Long Wavelength Semiconductor Disk Lasers for Continuous and Mode-Locked Operation

   Författare :Hans Lindberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mode-locking; thermal management; spectral properties; optically pumped; single frequency; beam quality; vertical-external-cavity surface-emitting laser; disk laser; Semiconductor laser;

   Sammanfattning : The semiconductor disk laser has recentlyemerged as an attractive alternative to bulky and power consuming gas and solid state lasers. It offers compact, powerful and efficient devices with W level output power and beam properties earlier not achieved with semiconductor lasers. LÄS MER
