摘要： Provided are an optical modulating device and a system including the optical modulating device. The optical modulating device includes a substrate, and a phase modulator formed on the substrate and including a Fabry-Perot cavity. The Fabry-Perot cavity of the phase modulator includes a first reflective layer, a second reflective layer, and a tunable core formed between the first reflective layer and the second reflective layer, wherein the tunable core is formed of a semiconductor material and is configured to modulate a phase of light corresponding to modulation of a refractive index of the tunable core according to electrical control.

摘要： An image sensor includes a substrate, thin lenses disposed on a first surface of the substrate and configured to concentrate lights incident on the first surface, and light-sensing cells disposed on a second surface of the substrate, the second surface facing the first surface, and the light-sensing cells being configured to sense lights passing through the thin lenses, and generate electrical signals based on the sensed lights. A first thin lens and second thin lens of the thin lenses are configured to concentrate a first light and a second light, respectively, of the incident lights onto the light-sensing cells, the first light having a different wavelength than the second light.
