초록

최근 조명 산업이 중요한 분야로 인식되면서 PQR (Photonic Quantum Ring) 소자는 LED(Light Emitting Diode)를 대체할 수 있는 차세대 광원이 될 전망이다. 본 연구에서는 기존 연구와 유사한 결과를 검증하고, 소자의 광특성을 분석하기 위해 광섬유가 연결된 스테이지에 x, y, z 좌표를 입력하면 자동으로 이동하며, 또한, 소자에 광섬유를 근접시키는 NSOM (Near field scanning optical microscopy) 장치를 추가한 측정 시스템을 이용하여 소자의 광특성 실험과 공진 및 어레이 소자의 광특성 시뮬레이션을 통해 조명용 소자로 가능성을 검증하고자 하였다. 이를 위해 메사와 홀 형태가 동시에 존재하는 메사 직경 40㎛, 홀 직경 3㎛의 소자를 제작하여 소자의 근접장으로 PQR 소자는 ㎂에서 동작하며, 메사와 홀 소자는 서로 독립적으로 구동됨을 관찰하였다. 위치에 따른 소자의 광파장 스펙트럼을 측정하여 메사와 홀 소자에 의한 커플링 현상을 처음으로 확인하였다.

We studies to verify results similar to those of previous experiments, and their potential as a lighting device through optical characteristics experiments and resonance and optical characteristics simulations of array devices. The photonic quantum ring (PQR) device having a mesa diameter of 40 ㎛ and an internal hole diameter of 3 ㎛ was fabricated. Through the near-field observation of the fabricated device, it was found that the PQR device operates even at ㎂, and also that the mesa and hole devices are driven independently of each other. As a result of measuring the wavelength spectrum of the device according to the location, the coupling phenomenon due to mesa and holes was confirmed.
