“…The thermo-optic temperature sensor also achieves the induction temperature change through this principle. Thermo-optic devices can be realized by interference-type Mach–Zehnder interferometers (MZIs) [ 13 , 14 ], multimode interference (MMI) [ 15 , 16 ], Michelson interferometers (MIs) [ 17 , 18 ], adiabatic evolution-type Y-branches [ 19 , 20 ], directional coupling (DC) [ 21 , 22 ], and total internal reflection (TIR) [ 23 , 24 ], as shown in Figure 1 .…”

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.

“…Therefore, the X-junction vertical structure optical switch has been proposed [ 15 , 16 , 17 ]. In 2018, Qian Qian Song fabricated an X-junction thermo-optic with a silicon oxynitride (SiON) core and polymer cladding, realizing a power consumption of 59.6 mW and rise and fall times of 1.42 ms and 0.85 ms, respectively [ 18 ]. Among the structures of X-junction optical switches, the organic–inorganic hybrid X-junction optical switch can realize the lower power consumption because of the different thermal optical (TO) coefficients of the polymer and inorganic material.…”

An inverted ridge 3D thermal optical (TO) switch of a graphene-coated polymer/silica hybrid waveguide is proposed. The side electrode structure is designed to reduce the mode loss induced by the graphene film and by heating the electrode. The graphene layer is designed to be located on the waveguide to assist in the conduction of heat produced by the electrode. The inverted ridge core is fabricated by etching and spin-coating processes, which can realize the flat surface waveguide. This core improves the transfer of the graphene layer and the compatibility of the fabrication processes. Because of the opposite thermal optical coefficient of polymer and silica and the high thermal conductivity of the graphene layer, the 3D hybrid TO switch with low power consumption and fast response time is obtained. Compared with the traditional TO switch without graphene film, the power consumption of the proposed TO switch is reduced by 41.43% at the wavelength of 1550 nm, width of the core layer (a) of 3 μm, and electrode distance (d) of 4 μm. The rise and fall times of the proposed TO switch are simulated to be 64.5 μs and 175 μs with a d of 4 μm, and a of 2 μm, respectively.
