A high Q-factor novel bulb design, to the best of our knowledge, inspired by the well-studied pulley microring resonator (MRR), is demonstrated and compared with circle and racetrack MRRs at wavelengths of 1.45-1.65 mu m. A wrapping of 60% around the ring showed a three times Q-factor increment ( Q = 828) compared to a standard circle MRR (Q = 206) at a telecom wavelength of 1.55 mu m with a fixed ring radius of 2 while further increasing the wrapping at 80% shows a decrease in its Q-factor (Q = 454). A comparison of the wavelength dependence of the bulb design with other typical MRR designs suggests that bulb designs are highly sensitive to wavelength and have very high Q-factors at lower wavelengths.
