• signal quality at the same time. An ac-voltage with 40 kHz and if not stated otherwise with a 2 V amplitude is overlaid over the dc-voltage during the whole measurement time. The ESM technique applied here does not use any resonance enhancement to amplify the ESM signal (such as dual resonance frequency

• dip around 1320 nm, which provides the bright mode. While the dark mode is excited by stub1, stub2 and the middle part of the bus waveguide between these two stubs, interacting with each other to get the first peak at 1066 nm, which is denoted as peak1. Based on the single mode system, a dual

• resonance mode system is constructed by side-coupling a rectangular resonator above stub1. The width and height of the rectangular resonator are 50 nm and 450 nm and the coupling distance g is 8 nm. The transmittance spectrum is shown in Figure 2b by the blue dashed line, where a second peak appeared at

• changing specific structural parameters. This independently tunable dual resonance is promising in the application of multi-parameter sensing. Next we investigate the effect of the refractive index on the transmission peaks. Since the left resonance peak is mainly influenced by the disk, we fill the disk
