PPT-Discussion today: Grating couplers

Today we will design and simulate a silicon photonic grating coupler using Lumerical FDTD Silicon photonic grating coupler design                 Optical fiber not to scale . However they are highly wavelength dependent A difference in wavelength of only 10nm can cause a significant change in the splitting ratio As a result it is important to specify the exact wavelength at which the fused coupler will be used Finally fu All models are available in plugin flatpack surface mount and connectorized SMA BNC Type N TNC option packages All units are designed and built to meet the environmental requirements of MILC15370 and are manufactured to ensure statistical control of ASTR 3010.

Diffraction: scattering of light by periodic structures. Wikipedia: a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. Today we will discuss how we can couple light between optical fibers and on-chip photonic waveguides. In particular we will focus on grating couplers.. Today we will cover the theory of grating couplers. Next week we will put the theory to use and design a silicon photonic grating coupler.
