In this paper, we design and demonstrate the optical encoder circuit. This device performs the function of encoding a 4- bit electrical signal into a 2-bit optical signal. The encoder structure is based on micro-ring resonator (MRRs) structures. A constant light (COS) is applied into an input port of the circuit, and depending on the electrical signals fed to heaters in MRRs; the input light is directed to different output ports. The performance of the proposed encoder is verified with the static and dynamic responses. The dynamic response of the encoder is tested up to 500Kbps. The proposed encoder is CMOS-compatible and can be manufactured using existing technologies that can be used for photonics computing and control.
