【 摘 要 】

We present numerical simulations of a novel microring resonator geometry, based on subwavelength hollow core defects inside the resonator cavity in order to study its influence on mode structure. The microring resonator has 9 μm outer diameter and 5 pm inner diameter, subwavelength defects are round shaped and have 100 nm diameter. Results allowed us to formulate basic approaches for controlling mode structure of ring microresonators.
