<p>An optical filter and a light splitting method of the optical filter are provided. The optical filter includes a beam incidence portion, a programmable Micro Electro-Mechanical System (MEMS) grating, a beam receiving portion, and a drive and control module, where relative positions of the beam incidence portion, the programmable MEMS grating, and the beam receiving portion are fixed and are set in order that the beam receiving portion is located in an emergence direction of the multi-wavelength beam after the multi-wavelength beam is incident onto the programmable MEMS grating from the beam incidence portion so that the beam receiving portion is capable of receiving a beam with a specific wavelength. The optical filter is capable of freely and conveniently selecting the beams with a specific wavelength, and meanwhile, the optical filter has the advantages of a small size, and being easily controlled and integrated.</p> |
