1. 1. Noncollinear optical parametric amplification of a supercontinuum

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Henrik Åkesson; [2019]
   Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

   Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE

4. 3. Direct Conversion Front End for LTE and LTE-A with Frequency-Translational Feedback, Harmonic Rejection Mixer and Input Matching Compensation

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Douglas Andersson Hägglund; [2016]
   Keywords : Technology and Engineering;

   Abstract : This thesis covers the design of a wideband, flexible front end for LTE and LTE-A in a 65 nm CMOS process. A topology with global frequency translational feedback is investigated and a harmonic rejection mixer is implemented. READ MORE

5. 4. Inductorless LNA and Harmonic-rejection Mixer for Wideband Direct-conversion Receiver

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Anh Chu; [2015]
   Keywords : Ericsson; inductorless; harmonic-rejection; Noise-cancelling LNA; Mixer; LNA; Receiver; LTE-A; 4G Network; Technology and Engineering;

   Abstract : In this master thesis, combinations of noise-canceling LNA and harmonic-rejection mixers are investigated and compared to find an optimal inductorless receiver front-end for low-band (600-960MHz) FDD LTE-A network. The work was carried out in a modem development project at Ericsson Modems, Lund. READ MORE

6. 5. Quantum Dynamics Simulations Using the Standard Matching Pursuit Gaussian Wavepacket Method : Practical Considerations

   University essay from Uppsala universitet/Teoretisk kemi

   Author : Erik Källman; [2014]
   Keywords : GSMP; wave packet; wavepacket; matching pursuit; quantum dynamics; TIDSE;

   Abstract : In any quantum dynamics method that approximates wave functions as a linearly combined basis set, non-orthogonality can be is a problem. It has been proven in previous studies that, by using the most standard form of Matching Pursuit in combination with a Gaussian wave packet ansatz, exact quantum-mechanical correspondence can be obtained for particle tunneling in one and two dimensions.
