Description
technical field [0001] The invention relates to the field of optical filtering, in particular to an optical filtering device, system and packaging structure. Background technique [0002] Tunable filter and attenuator: The dispersion element of the adjustable filter can be grating, liquid crystal or prism, etc. The dispersion element separates the different wavelength components of the incident light in space, and the output end selects a certain part of the spectrum to receive to achieve the filtering function. When the relative position of the input terminal and the output terminal in the dispersion process is changed controllably by a certain mechanism, the received spectral components are changed, that is, the function of adjustable filtering is achieved. The adjustable attenuation is to controllably change various losses between input light and output light, such as coupling loss, transmission loss, material absorption, etc. [0003] Tunable optical filter (TOF) & adju...
