“…To achieve a balance between power consumption and switching time, hybrid integration with the polymer core and inorganic cladding has been massively investigated. In 2014, Liang Lei fabricated the organic/inorganic hybrid MZI thermo-optic switch with a switching power of 7.2 mW and response time of 100 ms. 4 In 2014, Xie Nan fabricated low-power, high-speed polymer buried channel waveguide thermo-optic switches with a switching power of 3.5 mW and a response time of 200 ms. 5 The abovementioned hybrid devices take the materials into account, but the structures of cladding and substrate have not been optimized.…”

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.

“…In 2012, Yunfei Yan et al demonstrated a 2

2 thermo-optic switch based on the MMI-MZI structure, and the device required 6.2 mW per

shift power with a response time of 100 µs [ 12 ]. In 2014, Lei Liang et al fabricated a polymer/silica 2

2 directional coupler Mach–Zehnder interferometer (DC-MZI) thermo-optic switch with a switching power of 7.2 mW and a response time of ~100 µs [ 13 ]. Hybrid structured switches can take advantage of the complementary benefits of both materials, but at present, more hybrid structured switches use silica as the lower cladding and other different polymer materials as the core and upper cladding.…”

Taking advantage of the large thermo-optical coefficient of polymer materials, a hybrid-integrated thermo-optic switch was designed and simulated. It is also compatible with the existing silica-based planar light-wave circuit (PLC) platform. To further reduce the power consumption, we introduced the air trench structure and optimized the structural parameters of the heating region. This scheme is beneficial to solving the problem of the large driving power of silica-based thermo-optic switches at this stage. Compared with the switching power of all-silica devices, the power consumption can be reduced from 116.11 mW (TE) and 114.86 mW (TM) to 5.49 mW (TE) and 5.96 mW (TM), which is close to the driving power of the reported switches adopting polymer material as the core. For the TE mode, the switch’s rise and fall times were 121 µs and 329 µs. For the TM mode, the switch times were simulated to be 118 µs (rise) and 329 µs (fall). This device can be applied to hybrid integration fields such as array switches and reconfigurable add/drop multiplexing (ROADM) technology.
