1. 1. Optically poled fibers for electro-optic applications

   Författare :Joao Manoel Barbosa Pereira; Fredrik Laurell; Walter Margulis; Stavros Pissadaki; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : The work presented in this thesis shows the development of optically poleddevices for use in electro-optic experiments. In the form of papers published,it describes three optical poling methods: green light poling (Paper I), poling with a UV lamp (Paper II), and corona discharge poling (Paper V). LÄS MER

3. 2. Applications of monolithic fiber interferometers and actively controlled fibers

   Författare :Patrik Rugeland; Fredrik Laurell; Walter Margulis; Miguel Andrés; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber; fiber Bragg grating; micro-structured fiber; add drop multiplexer; fiber interferometer; microwave photonics; temperature sensor;

   Sammanfattning : The objective of this thesis was to develop applications of monolithic fiber devices and actively controlled fibers. A special twin-core fiber known as a ‘Gemini’ fiber was used to construct equal arm-length fiber interferometers, impervious to temperature and mechanical perturbations. LÄS MER
