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.

“…We developed the Mosquito method originally as a fabrication method for polymer optical waveguides with circular cross-sectional cores. Various types of polymer optical waveguides have been fabricated using the Mosquito method, such as symmetrical Y-branched core waveguides or three-dimensionally arranged cores [11,12]. In this paper, we designed and fabricated microchannels with circular cross-sections made of biocompatible and mechanically flexible PDMS (poly dimethyl siloxane) applying the Mosquito method to realize unique on-off valves.…”

In this paper, circular cross-section microchannels with 3-D lattice arrangements are designed and fabricated using the Mosquito method in order to construct on-off valves. The 3-D microchannels with on-off valves consist of two types of lines: the flow lines for chemical liquid flow and the control lines to activate the valves. We confirmed that both a circular cross-section and a PDMS with low elastic modulus used as the microchannel material contribute to a valve that can be closed with a lower pressure. Then, we demonstrated liquid flow to evaluate the functionality of the valve. Fluorescein solution was flown into a flow line. We found that the fluorescence intensity decreases at the intersection between the flow and control lines when the flow line is closed by the inflation of the control line, experimentally confirming the functionality of the valve microchannels fabricated via the Mosquito method.

“…The materials demonstrate minimal absorption loss, attributed to the lower density of carbon-hydrogen bonding within the resins. This PBS can be fabricated using the Mosquito method, as demonstrated in prior research [32,33]. In the fabrication, a liquid core monomer forms a coating within the silicon frame on the substrate.…”

In this research, a high-performance, polymer-based step-index composite coupler is designed and analyzed for integrated circuit applications, as it provides a critical tool for controlling the polarization of light, which is essential for a range of applications in optical communication systems. We examine the organic-inorganic hybrid polymer materials used to create the polymer-based composite beam splitter (CBS) at a 1.55 m wavelength with a step-index (SI) profile. We used the beam propagation and alternating direction implicit technique to develop and analyze the coupler. Our findings demonstrate that the suggested coupler successfully manipulates and analyzes its polarization dependency to attain a 99% output efficiency for the 50:50 splitting ratio utilizing a step-index (SI) profile. We enhanced the input intensity by about 56% for the SI profile with a 0.158 numerical aperture and a 31° input light angle. Additionally, the full width at half maximum was 4.67 and 7.74 degrees for φ=0 and 90 degrees, respectively. Without any polarization impact, we saw an excess loss of 0.014 dB, which rose to roughly 2 dB after polarization, and then fell to 0.05 dB at a 31-degree angle. Similar to the crosstalk, which was -25.06 dB without any polarization and changed to -19.77 dB at a 31-degree angle after polarization.
