“…4(a), when the electrode temperature is 298.145 K, the temperature of the waveguide core layer is 295.116 K. For the lower waveguide, as is shown in Figure 4(b), when the electrode temperature is 294.965 K, the temperature of the waveguide core layer is 293.598 K. We defined the heating efficiency of the electrode as α, according to Eq. 1 [22], we can calculate the heating efficiency of the two layers, respectively. When the initial temperature (T 0 ) is 293.15 K, the heating efficiency of the upper waveguide is calculated to be 39.36%, and the lower waveguide is 24.68%.…”

We present a polymer thermo-optic mode switch based on the structure of two vertical Mach-Zehnder interferometers (MZIs). It can achieve a rapid switch between E 00 , E 01 , E 10 and E 11 with the different heaters turning on. In our simulation, we compare two structures (the metal top electrode and the graphene electrode). The Finite element method (FEM) is used to simulate the parameters of the graphene electrode device. The power consumption of 1 and 3 heaters is 1.72 mW, and that of 2 and 4 heaters is 1.85 mW. In addition, the response speeds of the 1 and 3 graphene heater mode switch calculated are 36.9 μs (rise) and 103.4 μs (down), and that of 2 and 4 graphene heater mode switch calculated are 17.3 μs (rise) and 87.9 μs (down). The proposed model can be used in the field of low power consumption mode division and multiplexer of three-dimensional integrated.

“…Optical signal control is crucial in the optical transmissions. Signal control can be realized by the manipulation of a metal electrode, in turn achieving thermal optical or electrical optical switching functions [ 1 , 2 , 3 , 4 ]. The optically controlled method is another way of realizing the switch function.…”

All-optical devices have a great potential in optical communication systems. As a new material, graphene has attracted great attention in the field of optics due to its unique properties. We propose a graphene-assisted polymer optically controlled thermo-optic switch, based on the Ex01 mode, which can reduce the absorption loss of graphene. Graphene absorbs 980 nm pump light, and uses the heat generated by ohmic heating to switch on and off the signal light at 1550 nm. The simulation results show that, when the graphene is in the right position, we can obtain the power consumption of 9.5 mW, the propagation loss of 0.01 dB/cm, and the switching time of 127 μs (rise)/125 μs (fall). The switching time can be improved to 106 μs (rise) and 102 μs (fall) with silicon substrate. Compared with an all-fiber switch, our model has lower power consumption and lower propagation loss. The proposed switch is suitable for optically controlled fields with low loss and full polarization. Due to the low cost and easy integration of polymer materials, the device will play an important role in the fields of all-optical signal processing and silicon-based hybrid integrated photonic devices.
