Title:
VARIABLE WAVELENGTH FILTER, AND LIGHT RECEIVER AND LIGHT RECEIVING METHOD USING VARIABLE WAVELENGTH FILTER
Document Type and Number:
WIPO Patent Application WO/2018/084541
Kind Code:
A2
Abstract:
Disclosed are a variable wavelength filter, and a light receiver and light receiving method using the variable wavelength filter. An aspect of the present embodiment provides a light receiving module including a variable wavelength filter which allows light transmitted therethrough or reflected thereby to have a variable wavelength, the light receiving module comprising: a variable wavelength filter which allows only light having a pre-configured wavelength to transmit therethrough and can selectively change the pre-configured wavelength; a heat generating unit which is in contact with at least one surface of the variable wavelength filter; and a separating unit which has a pre-configured heat transfer rate, is in contact with at least a part of the variable wavelength filter to support the variable wavelength filter, and physically or thermally separates the variable wavelength filter from the other components in the light receiving module except for the heat generating unit, wherein the pre-configured wavelength is determined by a temperature of the heat generating unit.
