Abstract

The invention discloses a three-way optical component, which comprises a shell, a sleeve, photoelectric elements and optical filters, wherein the sleeve is connected to one of open pores on the shell; each of the photoelectric elements is arranged in one of the open pores and is associated with an optical signal; and each of the optical filters is arranged in the shell, corresponds to at least two photoelectric elements, is arranged on the optical path of the optical signal associated with at least two corresponding photoelectric elements, is penetrated by the optical signal associated with at least one corresponding photoelectric element and reflects the optical signals associated with the other corresponding photoelectric elements. The optical signals reflected by and penetrating the same optical filter are different in wavelength. By virtue of the optical filters, the three-way optical component transmits the optical signals that are different in wavelength and associated with the corresponding photoelectric elements through penetration or reflection.
