Abstract

The invention discloses a high-power bandwidth filter which comprises a box body, an optical input module, a first optical output module and a second optical output module which are arranged on the box body, and a band-pass optical filter arranged in the box body, wherein the first side face of the band-pass optical filter is plated with a band-pass film, the second side face of the band-pass optical filter is plated with an antireflection film, the included angle between the optical input module and the band-pass optical filter is equal to the included angle between the second optical output module and the band-pass optical filter, and the first optical output module is located on the extension line of the optical input module. The band-pass optical filter is arranged on a connecting line between the optical input module and the first optical output module, and a band-pass film of the band-pass optical filter faces the optical input module. The embodiment of the invention can improve the bearing power of the bandwidth filter, is good in heat dissipation effect, and can be widely applied to the technical field of optical devices.

Description

technical field [0001] The present invention relates to the technical field of optical devices, in particular to a high-power bandwidth filter. Background technique [0002] The fiber filter designed according to the principle of optical interference is mainly used to filter out the useless frequency (wavelength) components in the signal. For example: a narrow-band signal with a center wavelength of 1064 nm, which contains a larger range of other wavelengths of interference signals. With the demand for wavelength selection in the fields of optical fiber communication, optical fiber sensing, optical information processing, and fiber lasers, higher requirements are placed on the withstand power of the filter. However, the withstand power of filters in the current market is relatively low, and the dispersion effect is poor; it is difficult to find high-power filters that meet the needs of users in the existing optical filter market. SUMMARY OF THE INVENTION [0003] In view...
