  2. 1. 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

  4. 2. 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
