“…The experimental results indicated that the temperature sensitivity is 293.9 pm/°C, which is 6.3 times high- In terms of structures, MZI and MRR are the two fundamental structures of planar optical waveguide temperature sensors. The microring structure is shown in Figure 8a, which has the advantages of miniaturization and high sensitivity [87,88]. In 2010, Gun-Duk Kim et al used silicon to create an ultrasmall photonic temperature sensor with an MRR structure [89].…”

The thermo-optic effect is a crucial driving mechanism for optical devices. The application of the thermo-optic effect in integrated photonics has received extensive investigation, with continuous progress in the performance and fabrication processes of thermo-optic devices. Due to the high thermo-optic coefficient, polymers have become an excellent candidate for the preparation of high-performance thermo-optic devices. Firstly, this review briefly introduces the principle of the thermo-optic effect and the materials commonly used. In the third section, a brief introduction to the waveguide structure of thermo-optic devices is provided. In addition, three kinds of thermo-optic devices based on polymers, including an optical switch, a variable optical attenuator, and a temperature sensor, are reviewed. In the fourth section, the typical fabrication processes for waveguide devices based on polymers are introduced. Finally, thermo-optic devices play important roles in various applications. Nevertheless, the large-scale integrated applications of polymer-based thermo-optic devices are still worth investigating. Therefore, we propose a future direction for the development of polymers.

“…At an individual device level, measurements using side-of-fringe constant power mode, it has been shown that a noise floor below 100 µK is achieved using a free running laser [26]. Using wavelength-swept methods, measurements from cryogenic temperatures to above room temperatures have been demonstrated [26,149]. Packaging of the RR in a practical thermometer was reported to degrade the performance [22], however one of the possible reasons in that case was likely a residual porosity of the silicon-dioxide cladding layer and, as a result, sensitivity to the humidity.…”

The past decade saw the emergence of new temperature sensors that have the potential to disrupt a century-old measurement infrastructure based on resistance thermometry. In this review we present an overview of emerging technologies that are either in the earliest stages of metrological assessment or in the earliest stages of commercial development and thus merit further consideration by the measurement community. The following emerging technologies are reviewed: Johnson noise thermometry, optical refractive-index gas thermometry, Doppler line broadening thermometry, optomechanical thermometry, ﬁber-coupled phosphor thermometry, ﬁber-optic thermometry based on Rayleigh, Brillouin and Raman scattering, ﬁber-Bragg-grating thermometry, Bragg-waveguide-grating thermometry, ring-resonator thermometry, and photonic-crystal-cavity thermometry. For each emerging technology, we explain the working principle, highlight the best known performance, list advantages and drawbacks of the new temperature sensor and present possibilities for future developments.

“…Micro-ring resonators are widely used in optical filters [6][7][8] , micro-ring lasers [9,10] , optical switches [11] , and micro-ring sensors [12][13][14][15][16][17] due to their high-quality factor (Q factor), high sensitivity, and easy integration. In recent years, based on the research on micro-ring resonators, the sensitivity and output power of optical biosensors based on micro-ring resonators have been improved by the Vernier effect [18,19] .…”

Based on the Vernier effect of the cascaded double ring resonator (CDRR) sensor, a sensor consisting of a microfluidic control system, a sensing ring, and a reference ring with a micro-heater for thermal tuning is proposed in this paper. In wavelength interrogation, a broadband spectrometer or a large tunable range laser is not required. The shift of the output spectrum caused by the refractive index change of the sample is converted into the change of the electric power by the thermal tuning heater. Due to the Vernier effect, the sensitivity of the sensor is 20 times higher than that of the single ring. The spectral envelope of the thermal-optic tuning of the sensor was fitted by a Gaussian function in the wavelength range of 8 nm. The experimental results showed that the sensitivity was 33.703 W/RIU, and the limit of detection was 1.34 × 10 −5 RIU.
