Embodiment Construction

[0055] Various example embodiments will now be described more fully with reference to the accompanying drawings in which example embodiments are shown.

[0056] It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Expressions such as "at least one of," when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

[0057] It will be understood that although the terms "first", "second", etc. may be used herein to describe various elements, components, regions, layers and / or sections, these...

Abstract

Provided are an optical modulation device and an apparatus including the same. The optical modulation device may include a plurality of reflectors located on a driving circuit substrate, a plurality of nano-antennas located on the plurality of reflectors, and an active layer located between the plurality of reflectors and the plurality of nano-antennas and patterned to have a plurality of openings. The optical modulation device may further include a plurality of first connection members configured to electrically connect the driving circuit substrate to the plurality of reflectors and a plurality of second connection members configured to electrically connect the driving circuit substrate to the plurality of nano-antennas. The plurality of second connection members may be connected to theplurality of nano-antennas through the plurality of openings.

Description

technical field [0001] Apparatuses consistent with example embodiments relate to a light modulation device and an apparatus including the same. Background technique [0002] Optical devices for changing the transmission / reflection properties, phase, amplitude, polarization, intensity, path, etc. of light are used in a variety of different optical arrangements. Light modulators having various structures have been proposed to control such properties of light in a desired manner in an optical system. For example, liquid crystals with optical anisotropy or microelectromechanical systems (MEMS) structures using micromechanical movement of light blocking / reflecting devices are used in many light modulators. Such an optical modulator has the disadvantage of making the operation response time slow (for example, several μs or more) due to the characteristics of the driving method. [0003] Recently, attempts have been made to apply nanostructures utilizing surface plasmon resonance...
