Abstract We designed a reconfigurable dual-interferometer coupled silicon nitride microring resonator. By tuning the integrated heater on interferometer's arms, the "critical coupling" bandwidth of resonant mode is continuously adjustable whose quality factor varies from 7.9×104 to 1.9×105 with the extinction ratio keeping higher than 25 dB. Also a variety of coupling spanning from "under-coupling" to "over-coupling" were achieved, showing the ability to tune the quality factor from 6.0×103 to 2.3×105. Our design can provide an adjustable filtering method on silicon nitride photonic chip and contribute to optimize the nonlinear process for quantum photonics and all-optical signal processing.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
