Abstract

Provided is an optical modulator having pixelization patterns. The optical modulator includes an optical-electric (O-E) conversion element converting input optical images to current signals using the photoelectric effect, and an electric-optical (E-O) conversion element that emits light using the current signals transferred from the O-E conversion element. Trenches are formed from at least a surface of the optical modulator to a predetermined depth in the optical modulator so as to block or reduce electrical interference between pixels when the electric signals are transferred from the O-E conversion element to the E-O conversion element.

Description

technical field [0001] One or more exemplary embodiments relate to an optical modulator, and more particularly, to an optical modulator having a pixelization pattern to obtain image modulation with high resolution. Background technique [0002] Optical-Electrical-Optical (O-E-O) modulators receive optical information (images) to convert optical information into electrical information, modulate electrical information, and output optical information (images), optical-electrical-optical (O-E-O) modulators can have the following Performs the functions of modulating, converting wavelength, and amplifying light at high speed, therefore, optical-electrical-optical (O-E-O) modulators have been used as core components in three-dimensional (3D) cameras, laser radar (LADAR), infrared (IR) imaging . [0003] The O-E-O modulator is operated by a mechanism of receiving an image having a wavelength of about 800nm ​​to 1700nm (i.e., infrared (IR) band), generating a current using the photo...
