With the development and application of Internet of things, new requirements for optical communication technology are put forward, and this text proposed new optical information processing device design logic-oriented-based for Internet of brain things application. Three micro rings were coupled with three different shapes of optical waveguide components, their wavelengths were varied with the change of the applied voltages (logical input) so as to control the propagation direction of the input optical signal and the final output forms of lighting or darkness representing different logic level values as the result of the logical operations. The working wavelength of the device was determined as $1.5146~\mu \text{m}$ through static simulations with MATLAB tools, and it was proved that the functions of flexible optical switch logic operations “and/not”, “or/nor”, and “xor/xnor” can be realized in the dynamic simulations, the results indicated that the device with low-power consumption, high-bandwidth, flexible structure, and multiple logical operation functions has been accomplished and can be used as components of VLSI designs in future. This paper also gives a useful reference to many Internet of brain things applied field.
