We demonstrate a highly compact third-order elliptical micro-ring add-drop filter based on a silicon-on-insulator wafer.The elliptical micro-ring resonator has a major radius of 6μm(minor radius of 4.112 μm)and a large free spectral range of 18 nm.Experimental results show a box-like channel dropping response,which has a 3 dB bandwidth of ~2.7 nm,high out-of-band signal rejection of around 40 dB and a very low drop loss(<0.5 dB).Simulation agrees well with the experiments.The footprint of the whole chip is only 0.0003 mm~2.
