The purpose of this report is to design, fabricate and test a group of TE silicon photonics devices using Klayout, Lumerical Interconnect and measurement analysis. The report is also going to introduce some basic design concept of a photonic device, an is going to observe the effect of different waveguide parameters on the performance of the device. An indirect relationship between refractive index (either group or effective) and wavelength is going to be developed in this report. Later on, we are going to compare the result from simulation with the measurement result by plotting the same transmission curve and extracting device parameters from measurement data.
