  5. 13. Wafer-scale Vacuum and Liquid Packaging Concepts for an Optical Thin-film Gas Sensor

    Author : Mikael Antelius; Göran Stemme; Yogesh B. Gianchandani; KTH; []
    Keywords : Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; packaging; vacuum packaging; liquid encapsulation; integration; wire bonding; grating coupler; waveguide; Fabry-Perot resonator;

    Abstract : This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. READ MORE

  6. 14. Integrated Nanophotonic Devices in Lithium Niobate

    Author : Mohammad Amin Baghban; Katia Gallo; Fabrice Raineri; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium niobate LN ; LN-on-insulator; photonic integrated circuits; nonlinear optics; electro-optics; waveguides; propagation losses; Bragg gratings; grating couplers; polarization-insensitive; LN for life sciences; Fysik; Physics;

    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. 15. Dynamic and Static Diffractive Optics - some Examples

    Author : Björn Löfving; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subwavelength grating; spatial light modulator; phase retrieval; diffractive optics; ferroelectric liquid crystal; analog-to-digital conversion; optical switch; feedback generated hologram;

    Abstract : Diffractive optics is a modern branch of optics, that exploits microstructures to manipulate the propagation of light. Fast computers and the progress in manufacturing technique of microelectronics have made possible a rapid development of diffractive optics during the past 10 years. READ MORE
