    Abstract: The light detector includes a light detection substrate having at least one light receiving region and a light incident surface on which a detection target light is incident, and a meta-lens including a plurality of unit structures arranged in a grid pattern and disposed on the light incident surface to focus the detection target light. When viewed in a thickness direction of the light detection substrate, an opening region in which no unit structure is formed is provided in a region including a center of the meta-lens.

    Abstract: The present embodiment relates to a light-emitting device that enables reduction in attenuation or diffraction effect caused by a semiconductor light-emitting device with respect to modulated light outputted from a spatial light modulator, and the light-emitting device includes the semiconductor light-emitting device that outputs light from a light output surface and the reflection type spatial light modulator that modulates the light. The spatial light modulator includes a light input/output surface having the area larger than the area of a light input surface of the semiconductor light-emitting device, modulates light taken through a region facing the light output surface of the semiconductor light-emitting device in the light input/output surface, and outputs the modulated light from another region of the light input/output surface to a space other than the light input surface of the semiconductor light-emitting device.
