StretchBio_D5.1 – REPORT ON THE DESIGN AND FABRICATION ISSUES OF THE OPTICAL GRATING

Year: 2024

Type: article

Abstract: This deliverable presents the results of the simulation of grating coupler designs on an SOI platform to efficiently couple light from a single-mode fiber into a low-loss single-mode waveguide and the upcoming fabrication challenges, especially with regards to fabrication compatibility with the photonic crystal device. It reports the coupling efficiencies and bandwidths of different coupler designs depending on the wavelength to address, which is given by working in air or water. It also includes the design of an adiabatic linear taper for efficient mode-field matching from a single-mode fiber (mode-field diameter of roughly 10 μm) to a single-mode waveguide (500 x 400 nm2).
