“…The temperature sensors that use the single resonator have been reported [ 26 , 27 ], in which the temperature variation was measured by monitoring the shift in the resonant wavelength of the silicon resonator. However, the temperature variations will induce the thermo-optic effect and the thermal expansion effect simultaneously.…”

“…However, due to the small size of these structures, it is challenging to detune optical cavity for controlling of the resonant interaction between the two optical pathways. For instance, the two paralleled resonators [ 26 ] require an ~8 nm perimeter difference between the two rings, which is normally very challenging to control in the fabrication.…”

The analogue of electromagnetically induced transparency in optical methods has shown great potential in slow light and sensing applications. Here, we experimentally demonstrated a coupled resonator induced transparency system with three cascaded ring coupled resonators in a silicon chip. The structure was modeled by using the transfer matrix method. Influences of various parameters including coupling ratio of couplers, waveguide loss and additional loss of couplers on transmission characteristic and group index have been investigated theoretically and numerically in detail. The transmission character of the system was measured by the vertical grating coupling method. The enhanced quality factor reached 1.22 × 105. In addition, we further test the temperature performance of the device. The results provide a new method for the manipulation of light in highly integrated optical circuits and sensing applications.

“…However, the fabrication process is complicated and the PCFs are also expensive. To solve those problems, optical waveguide temperature sensors using various polymer materials have attracted increasing interest [16][17][18]. These temperature sensors were extensively studied and have potential applications owing to their low cost, simple fabrication process, easy integration, and high sensitivity [19].…”

A highly sensitive waveguide temperature sensor based on asymmetric Mach–Zehnder interferometer was designed and experimentally demonstrated. The interferometer is based on the polymer/silica hybrid waveguide structure, and Norland Optical Adhesive 73 (NOA 73) was employed as the waveguide core to enhance the temperature sensitivity. The influence of the different length differences between the two interferometer arms on the sensitivity of the sensor was systemically studied. It is shown that the maximum temperature sensitivity of −431 pm °C−1 can be obtained in the range of 25 °C−75 °C, while the length difference is 92 μm. Moreover, the temperature sensitivity contributions from different core materials were also investigated experimentally. It is shown that the waveguide material and microstructure of the device have significant influences on the sensitivity of the waveguide temperature sensor.
