  2. 1. Carbohydrate Synthesis and Study of Carbohydrate-Lectin Interactions Using QCM Biosensors and Microarray Technologies

    Author : Zhichao Pei; Olof Ramström; Roland J. Pieters; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lectins; Carbohydrates; Molecular recognition; Biosensors; Quartz crystal microbalance; Carbohydrate microarrays.; Organic chemistry; Organisk kemi;

    Abstract : Interactions between carbohydrates and proteins are increasingly being recognized as crucial in many biological processes, such as cellular adhesion and communication. In order to investigate the interactions of carbohydrates and proteins, the development of efficient analytic technologies, as well as novel strategies for the synthesis of carbohydrates, have to be explored.

  4. 2. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

    Author : Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

    Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE

  5. 3. Ultralow-loss silicon nitride waveguides for nonlinear optics

    Author : Zhichao Ye; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultralow loss; Kerr nonlinear optics; parametric amplifier; DKS microcombs; integrated waveguides; silicon nitride;

    Abstract : The field of nonlinear optics relies on the interaction between high-intensity optical waves and nonlinear media. An integrated waveguide with large refractive index contrast allows to highly confine optical waves in a sub-μm^2 area, thus enhancing the optical intensity. READ MORE

  6. 4. Frequency combs on chip for interferometry applications

    Author : Israel Rebolledo Salgado; Martin Zelan; Victor Torres-Company; Karsten Rottwitt; RISE; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical frequency combs; microcombs; pulses; nonlinear optics; interferometry; integrated photonics; spectroscopy;

    Abstract : Optical frequency combs have revolutionized the field of laser spectroscopy. A frequency comb is a type of laser that generates an array of equally spaced coherent laser lines. Indeed, the outstanding performance of frequency combs in terms of bandwidth and stability is readily attainable in bench-top systems. READ MORE
