Resonators and Waveguides for Fiber Optics and Integrated Photonics – Presented by Ali Serpenguzel, Koç University

Resonators and Waveguides for Fiber Optics and Integrated Photonics – Presented by Ali Serpenguzel, Koç University, at the Photonic Integration Conference 2018, which will take place on October 2, at High Tech Campus Eindhoven, The Netherlands.

Spherical optical microcavities are the building blocks of three dimensional photonics, as linear optical microcavities are the building blocks of one dimensional photonics. Dielectric and semiconductor based lightwave circuit elements are being integrated into fiber optics and integrated photonics. Silicon microspheres lead themselves to various lightwave circuit element applications such as channel dropping filters, tunable filters, and optical modulators using optical fiber half couplers manufactured from single mode optical fibers.

Silicon on oxide (SOI)-distributed feedback (DFB) meandering waveguides, as novel integrated optical elements, can exhibit a variety of spectral responses such as coupled resonator induced transparency filter, Fano resonator, hitless filter, Lorentzian filter, Rabi splitter, self coupled optical waveguide, and tunable power divider.

We focus on properties of various novel resonators, such as diamond spheres, and SOI-DFB meandering waveguides, and their potential for practical applications in optics and photonics.
