Characteristic Research of SOI Rib Waveguide Resonators with SiO2 Deposited

Article Preview

Abstract:

With the extensive research and application of SOI nano-optical ring resonators, the problem of high integration becomes the bottleneck restricting its development. To research the effect of deposited SiO2 insulating layer on the resonance characteristic of SOI nano-waveguid ring cavity while integrating, a rib waveguide ring resonator with 500nm SiO2 insulating layer deposited was designed and fabricated in this paper. By testing the resonance transmission spectrum power of this structure, it is found that SiO2 insulating layer deposited has no effect on the grating vertical coupling efficiency while improves the quality factor to 14.000±1.000.
