시간-공간 변환을 통한 단일 샷 역다중화의 원리는 스쿠릴륨 염료(SQ) J-응집체의 흡수 표백의 펨토초 비선형 광학 응답을 사용하여 조사되었습니다. 유리 기판에 스쿠릴륨 염료 J-응집체를 스핀코팅한 필름은 효율적이고 초고속 투과율 변화를 나타내며, 이는 73 ps 이내에 초기 수준(0 fs)의 1%를 복구합니다. 이 영화에는 시간을 공간으로 변환하는 간단한 방법이 적용되었습니다. 우리는 펨토초 펄스의 특성 중 하나인 전파 방향의 공간적 얇음에 주목했습니다. 단일 펌프 펄스의 펨토초 펄스와 10개의 프로브 펄스 열이 SQ J-응집체 필름 표면의 동일한 영역(직경 1mm)에 조명되었습니다. 프로브 빔의 방향은 필름 표면에 수직이었고 펌프 빔의 방향은 수평면에서 비스듬한 각도였습니다. 필름에 대해 비스듬한 각도의 조명으로 인한 펌프 펄스의 공간적 지연으로 인해 1 ps(1 THz) 간격 시간을 가진 XNUMX개의 프로브 펄스가 필름의 별도 위치에서 만납니다. SQ J-응집체의 빠른 응답으로 인해 필름은 필름의 투과율 변화로 인해 초기 원형에 비해 수평 방향으로 더 좁은 모양을 갖는 각 프로브 펄스의 일부를 선택했습니다. 공간적으로 분리된 XNUMX개의 라인은 전송된 프로브 펄스 트레인의 이미지를 위해 CCD 카메라로 관찰되었습니다. 이러한 결과는 각 라인의 수평 폭을 결정하는 SQ J-aggregate 필름의 응답 시간이 XNUMXTHz 광 신호의 역다중화에 충분함을 시사합니다.

Abstract: Principle of a single shot demultiplextion by means of time-to-space conversion was investigated using femtosecond nonlinear optical response of absorption bleaching of squarylium dye (SQ) J-aggregates. Spincoated films of squarylium dye J-aggregates on glass substrates exhibit efficient and ultrafast transmittance change, which recovers 73% of its initial level (0 fs) within 1 ps. A simple method for time-to-space conversion was applied for this film. We took our attention to one of the characteristics of femtosecond pulse, which is the spatial thinness in its propagation direction. Femtosecond pulses of a single pump pulse and train of four probe pulses were illuminated to the same area (diameter of 10 mm) of the surface of the SQ J-aggregates film. Direction of the probe beam was normal to the surface of the film and that of the pump beam was oblique angle in horizontal plane. Caused by spatial delay of a pump pulse due to the illumination in oblique angle to the film, four probe pulses with interval time of 1 ps (1 THz) meet separate places on the film. Because of the fast response of the SQ J-aggregates, the film picked out part of each probe pulse, which has narrower shapes in horizontal direction compared to the initial circular one by transmittance change of the film. The spatially separated four lines were observed by a CCD camera for an image of the transmitted probe pulse train. These results suggest that the response time of SQ J-aggregate film, which determines the horizontal width of each line, to be enough for demultiplexing of 1 THz optical signals.
