우리는 이전에 광섬유 브래그 격자(FBG) 위상 인코더/디코더를 사용하는 코히어런트 광 코드 분할 다중화(OCDM) 시스템에 대해 신호가 광원 파장과 FBG 위상의 브래그 파장 간의 차이에 대한 위상 변이 허용 오차를 나타냈다고 보고했습니다. 두 신호가 다중화되었을 때의 인코더/디코더. 다만, 펄스를 형성하는 파장 중 중심 파장의 위상 조건만을 분석하였다. 보다 구체적인 고려 사항을 위해 디코딩된 펄스를 형성하는 각 파장의 위상을 계산했습니다. 본 보고서에서는 측정 및 계산된 반사 특성을 비교하고 방법의 신뢰성을 확인했습니다. 디코딩된 펄스의 위상 조건을 계산하고 위상 변조와 디코딩 시 중첩되는 펄스 간의 간섭에 대한 위상 특성을 명확히 했습니다. 비동기식 액세스를 구현하려면 확산 시간이 2의 역수가 되도록 FBG 위상 인코더/디코더를 설계해야 합니다.

Abstract: We previously reported, for a coherent optical code division multiplexing (OCDM) system using fiber Bragg grating (FBG) phase en/decoders, that the signals exhibited phase shift tolerance for a difference between the light source wavelength and the Bragg wavelength of an FBG phase en/decoder when the two signals were multiplexed. However, the phase conditions of only the central wavelength among the ones forming a pulse were analyzed. For a more specific consideration, we calculated the phase of each wavelength forming the decoded pulse. In this report, the measured and calculated reflecting properties were compared and the reliability of the method was confirmed. We calculated the phase conditions of the decoded pulses and clarified the phase characteristics with regard to the phase modulation and the interference between pulses overlapped during decoding. For the realization of an asynchronous access, the FBG phase en/decoders should be designed so that the spreading time is the inverse of 2
