Abstract :
An important feature for the Micro-resonator is the quality factor. This Paper presents a new equilateral triangle micro-resonator (ETR) design, simulates the spectral response by FDTD method, then calculates the quality factor (Q factor), and compare the results with the micro-ring resonator (MR) with similar footprint. The simulation results show that the quality factor of ETR at the side length of 6um is more than 10 times larger than that of the MR which has the same area as ETR on the same material platform. We also show that the output of an ETR with an opening to the output waveguide is more efficient, besides the increasing of quality factor by 26% at a wavelength of 1.48um.
