1. Forward error correction as equalization method
University essay fromAbstract : The instant demand to achieve high data rate in communication systems is driving the high-speed links into multi Gigabit per second data transitions, where its suffering from inter symbol interference due to bandwidth limitation. Equalizers are used at both the transmitter and receiver side of the link to counteract signal attenuation, reflections, crosstalk and any type of distortion of the signal. READ MORE

2. Towards the carrier-envelope phase stabilization of a16 TW 4.5 fs laser system
University essay from Umeå universitet/Institutionen för fysikAbstract : In the last decades the scientific development has made it possible to produce pulses with durations below the femtosecond time scale (1 fs = 1015 s), reaching to attoseconds (1 as = 1018 s). This is the time scale of electronic motion inside atoms and molecules. READ MORE

3. Compression and Shaping of Femtosecond Laser Pulses for Coherent Two-Dimensional Nanoscopy
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikAbstract : Femtosecond pulse shaping is a versatile tool that enables the generation of ultrashort laser pulses with nearly arbitrary temporal shapes. Among others, the technique is of use in ultrafast spectroscopy experiments where it can be employed for dispersion control and the generation of well-defined laser pulse sequences. READ MORE

4. Investigation of the chirp properties of DFB-EAM’s for high speed baseband and RoF transmission links
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : The ever increasing bandwidth demands driven by an explosion in the mobile device market calls for more and more optical and wireless convergence due to the ability of optical communication systems to transport larger amounts of information to longer distances. Optical modulators are in charge of performing the electrical-to-optical domain conversion, which place them as one of the critical components in optical communication systems. READ MORE

5. FPGA Implementation of an Interpolator for PWM applications
University essay from Institutionen för systemteknikAbstract : In this thesis, a multirate realization of an interpolation operation is explored. As one of the requirements for proper functionality of the digital pulse-width modulator, a 16-bit digital input signal is to be upsampled 32 times. To obtain the required oversampling ratio, five separate interpolator stages were designed and implemented. READ MORE
