Abstract

We propose a 650/1550nm wavelength Mux/DeMux for SS-OCT system based on silica-on-silicon (SoS), in which mixing red/infrared lightbeams can be fully separated at low insert loss through special cascaded multimode interference (MMI) structure. Each independent lightbeam is entered into its respective channel by selecting proper width and length of the MMI. By using of Finite Difference Beam Propagation Method (FD-BPM), the Mux/DeMux is optimally designed in size of 1×0.1cm², working at 650nm and 1550nm simultaneously. The results show the degrees of separation between two lightwaves are super high, loss of infrared light is less than 0.5dB and 1dB, and its output power stability is less than 0.25dB and 0.8dB, in 1510nm -1570nm and in 1500nm -1600nm, respectively. The Mux/DeMux can be used in SS-OCT PIC based on SoS.
