This paper presents a visible three-wavelength combiner based on directional coupling. The device consists of two cascaded directional couplers. It can achieve the synthesis of three-wavelength visible bands. As an example, a three-wavelength combiner to combine 635 nm, 532 nm and 488 nm wavelength channels are proposed in this paper. The size of the entire device is 2500um. The simulation by BeamPROP software shows that the inser-tion loss of each wavelength is less than 0.15dB.
