6. Integrated Nanophotonic Devices in Lithium Niobate
Abstract : Lithium niobate (LN) is a ferroelectric crystal offering a broad transparency spectrum, together with excellent electro-optic and nonlinear optical properties. Thanks to them, LN is setting the standard for quantum optics and telecommunications in critical applications such as ultrafast modulation and frequency conversion. READ MORE

7. Thermal properties of volume Bragg gratings and its implications on lasers
Abstract : This thesis contains the results of research on the spectral control of lasers, specifically, the thermal limitations of volume Bragg gratings (VBGs), employed as laser-cavity end mirrors. The investigations consisted of both experiments and numerical simulations. READ MORE

8. Spectral control of lasers and optical parametric oscillators with volume Bragg gratings
Abstract : I den här avhandlingen visas hur lasrar och optiska parametriska oscillatorer (OPO:er) kan styras spektralt med hjälp av volymbraggitter. Volymbraggitter utgörs av ett periodiskt varierande brytningsindex som skrivits i ett fototermorefraktivt glas. READ MORE

9. All-fibre optical sensor system for chemical sensing based on fibre Bragg grating technology
Abstract : This thesis deals with the realization of an all-fibresensor system for chemical sensing through the evanescentfield, based on fibre Bragg grating technology. The advantagesof all-fibre systems are most apparent for the potential userof the system. These systems are of small size, have highmobility, and require no precision alignment. READ MORE

10. Applications of monolithic fiber interferometers and actively controlled fibers
Abstract : 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. READ MORE
