MZI-assisted-MRR filter with a tunable bandwidth and dip wavelength on the LNOI platform

【摘要】 We propose and demonstrate experimentally a tunable filter based on a Mach-Zehnder interferometer [MZI)-assisted microring resonator [MRR) formed on the lithium niobate on insulator [LNOI) platform. Our proposed filter can achieve electro-optic[EO) and thermo-optic [TO) tuning for the bandwidth and the dip wavelength simultaneously. Our typically fabricated filter shows that the minimum and maximum 3 dB bandwidths at the through port are 27.86 and 31.74 GHz, respectively, while at the drop port, these values are 14.68 and 30.69 GHz. Meanwhile, the TO and EO tuning rates of the dip wavelength are approximately-6.5 pm/mW and-65.09 pm/V, respectively. Our proposed filter has the potential to be used in optical communication and optical information processing systems to achieve multifunctional filtering characteristics.更多还原
