  2. 1. Bismuth iron garnet films for magneto-optical photonic crystals

    Author : Sören Kahl; KTH; []
    Keywords : Faraday effect; iron garnet; pulsed laser deposition; photonic crystals;

    Abstract : The thesis explores preparation and properties of bismuthiron garnet (BIG) films and the incorporation of BIG films intoone-dimensional magneto-optical photonic crystals (MOPCs). Films were prepared by pulsed laser deposition. READ MORE

  4. 2. Fibre Optic Magnetic Field Sensors Utilizing Iron Garnet Materials

    Author : Hans Sohlström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yig; iron garnets; rare earth garnets; magneto-opics; optical waveguide; fibre optical sensors; magnetic field measurement; current measurement;

    Abstract : This thesis deals with the subject of fibre optic magnetic field sensors utilizing iron garnet materials. Such materials exhibit a large Faraday rotation which make them advantageous for application in compact mag­netic field sensors. READ MORE

  5. 3. Complex Oxide Photonic Crystals

    Author : Dzmitry Dzibrou; Alex Grishin; Peter Lazor; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonic crystals; magneto-optical effects; refractive index; iron garnet; Optics; Optik;

    Abstract : Microphotonics has been offering a body of ideas to prospective applicationsin optics. Among those, the concept of photonic integrated circuits (PIC’s) has recently spurred a substantial excitement into the scientific community. Relisation of the PIC’s becomes feasible as the size shrinkage of the optical elements is accomplished. READ MORE
