  1. 6. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes

    University essay from Linköpings universitet/Informationskodning

    Author : Martin Clason; [2023]
    Keywords : shot noise; quantum random number generator; photodiode; transimpedance amplifier; skottbrus; kvantslumptalsgenerator; fotodiod; transimpedansförstärkare;

    Abstract : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. READ MORE

  3. 7. Development of Detachable Audio Accessory for Surveillance Cameras

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Eric Hammar; Pontus Sjöstrand; [2023]
    Keywords : Technology and Engineering;

    Abstract : Surveillance cameras are used for video monitoring. To complement the video stream, different external accessories can be attached to a camera. The addition of external accessories brings certain limitations in terms of aesthetics and functionality. READ MORE

  4. 8. Photoluminescence Mapping of Erbium Doped Lithium Niobate

    University essay from KTH/Tillämpad fysik

    Author : Chuanshi Xie; [2023]
    Keywords : Automotive mapping; Erbium emitters; Ion implantation; Lithium niobate on insulator; photoluminescence microscopy; Automatisk kartläggning; Erbium fotonemitterare; Jonimplantation; Litiumniobat på isolator; fotoluminiscensmikroskopi.;

    Abstract : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

  5. 9. Joint CFR and DPD optimization for 5G Digital Front Ends

    University essay from Lunds universitet/Matematik LTH

    Author : Gustav Olsson; [2023]
    Keywords : Crest Factor Reduction; Digital Pre-Distortion; Power Amplifier; Parameter Optimization; 5G; Base Station; Memory Polynomial; Technology and Engineering;

    Abstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.
