Embodiment Construction

[0028] Figure 4 It is a schematic diagram showing a Fabry-Perot optical filtering device 1 according to a preferred embodiment of the present invention. Such as Figure 4 As shown, the optical filter component module 2 of the Fabry-Perot optical filter device 1 of this embodiment includes at least one Fabry-Perot component 201 and n reflective components 202 , where n≧1. In addition, the Fabry-Perot optical filtering device 1 of this preferred embodiment also includes an input end 203 and an output end 204, which are respectively used to introduce a1 ~λ n The input optical signal and the derived one with a specific wavelength λ i output light signal.

[0029] According to the optical filtering operation principle of the Fabry-Perot component, when one has a wavelength of λ 1 ~λ n When the input light is introduced into a Fabry-Perot component, we can obtain a specific wavelength λ by adjusting the distance between the two reflective surfaces in the Fabry-Perot component ...

Abstract

The Fabry-Perot optical filter device includes one Fabry-Perot assembly for light to pass through and to be treated in at least two times of optical filtering; several reflecting assemblies inside the optical filters to reflect the light passing through the Fabry-Perot assembly back to the Fabry-Perot assembly. The Fabry-Perot optical filter device also includes one input end to guide the light to the Fabry-Perot optical filter device and one output end to guide out the light after two times of optical filtering.

Description

technical field [0001] The present invention relates to an optical filter device, in particular to a Fabry-Perot optical filter device, which consists of a Fabry-Perot component with the same operating principle as a Fabry-Perot interferometer and reflective components. Background technique [0002] The development of optical communication systems is a main axis in the technical field in recent years. Due to the discovery of optical fiber, the maturity of semiconductor process technology, and the development of micro-electromechanical manufacturing technology, it has contributed to the continuous progress of the development of optical communication systems. [0003] The basic principle behind optical communication systems is to use the travel of light waves to transmit information, known as optical signals. In the process of information transmission, the efficiency of sending and receiving information is closely related to the characteristics of light waves. Generally spe...
