1. 1. High-efficiency dissipative Kerr solitons in microresonators

   Författare :Òskar Bjarki Helgason; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissipative Kerr solitons; dissipative solitons; nonlinear optics; microresonators; microcombs; optical frequency combs;

   Sammanfattning : The microresonator comb (microcomb) is a laser source that generates equally spaced coherent lines in the spectral domain. Having a chip-scale size and the potential of being low cost, it has attracted attention in multiple applications. LÄS MER

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

   Författare :Zhichao Ye; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
