Title:
LIGHT MODULATION ELEMENT AND LIGHT DETECTION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/061679
Kind Code:
A1
Abstract:
This light modulation element is provided with: a fixed wavelength filter that has a transmission wavelength band and a non-transmission wavelength band; and a variable wavelength filter that changes the wavelength band to be transmitted between the transmission wavelength band and the non-transmission wavelength band of the fixed wavelength filter and that comprises a function unit provided with a single chip element having two substrates that respectively support a pair of reflection mirrors opposingly arranged apart from each other by a gap g and an actuator that changes the gap g, and an actuator control circuit unit that supplies a driving voltage to the actuator, wherein the fixed wavelength filter is directly formed on the surface of one of the two substrates.
