Title:
LIGHT RECEIVING ELEMENT, IMAGING ELEMENT, AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/153298
Kind Code:
A1
Abstract:
The present technology relates to a light receiving element, an imaging element, and an imaging device in which a reduction in the size of the light receiving element receiving infrared light has been achieved. The present invention includes: a conversion unit for converting incident light into light with a first wavelength band; and a photoelectric conversion unit for receiving the light with the first wavelength band as a result of the conversion by the conversion unit and performing photoelectric conversion. A first surface of the conversion unit on the photoelectric conversion unit side is subjected to surface plasmon resonance in the first wavelength band, and a second surface of the conversion unit on which light is made incident is subjected to surface plasmon resonance in a second wavelength band. The present technology can be applied to, for example, a light receiving element that receives infrared light and that has a reduced size and a reduced height.
