The performances of enhanced micro-ring resonators on a silicon on insulator platform are reported. The ring resonators are composed using four low-loss advanced bends with $1\mu \text{m}$ -straight waveguides between the bends. The losses of advanced bends are nearly ten and fifteen times lower than those of normal bends when radii of bends are 2 and $3\mu \text{m}$ , respectively. The effective radii ( $R_{eff}$ ) of the racetrack-rings are 2.5 and $3.5\mu \text{m}$ using advanced bends with 2 and $3\mu \text{m}$ -radii, respectively. The quality factor( $Q$ ) of 7800, finesse ( $f$ ) of 175, free spectral range ( FSR ) of 35nm, and extinction ratio ( ER ) of >11dB have been measured from the racetrack ring resonator with $R_{eff}$ of $2.5\mu \text{m}$ . From the racetrack ring resonator with $R_{eff}$ of $3.5\mu \text{m}$ , we obtained the $Q$ of 19000, the $f$ of 287, the FSR of 23nm, and the ER of >10dB at C-bands.
