Abstract

The present invention provides a filter which includes a first reflecting plate and a second reflecting plate, a dielectric area which is interposed between the first reflecting substrate and the second reflecting substrate and on which at least two materials with different refractive indexes are arranged, and a buffer which is installed between the dielectric area and at least one of the first and second reflecting substrates. There are at least two areas with different relative volume ratios of the two materials.

Description

technical field [0001] The present invention herein discloses an optical filter, and more particularly, an optical filter for controlling a transmission center wavelength with a relatively simple and small structure and an optical device using the optical filter. Background technique [0002] A linear variable filter (LVF) is an optical filter with a Fabry-Perot resonator structure, which has a structure in which the thickness of the cavity changes linearly along the length direction. In LVF, a lower mirror layer and an upper mirror layer are provided with a dielectric cavity in between. [0003] Such LVFs have limitations in process reproducibility due to the linear structure in which the thickness varies along the length direction. Furthermore, the resolution of a spectrometer using a typical LVF is determined by the height-length ratio of the LVF, making it difficult to minimize spectrometer components. In particular, this is detrimental to productivity due to the linea...
