Abstract | To provide an optical modulator and a beam steering system comprising the same.SOLUTION: The present invention relates to an optical modulator including a plurality of unit cells, and a beam steering system comprising the same. The optical modulator comprises an active layer having a refractive index that changes according to an electrical signal applied thereto, a plurality of antenna patterns provided over the active layer, and a mirror layer provided under the active layer, where the active layer includes a plurality of refractive index changing areas that are structurally separated from each other.SELECTED DRAWING: Figure 3
【課題】光変調器、及びそれを含むビームステアリングシステムを提供する。【解決手段】複数の単位セルを含む光変調器、及びそれを含むビームステアリングシステムに係り、該光変調器は、電気的な信号によって屈折率が変化する活性層と、活性層の上部に設けられる複数のアンテナパターンと、活性層の下部に設けられるミラー層と、を含み、ここで、該活性層は、構造的に互いに分離されるように設けられる複数の屈折率変換領域を含む。【選択図】図3 |
