Prinsip demultiplextion pukulan tunggal melalui penukaran masa ke ruang telah disiasat menggunakan tindak balas optik tak linear femtosaat pelunturan penyerapan pewarna squarylium (SQ) J-agregat. Filem bersalut squarylium pewarna J-agregat pada substrat kaca mempamerkan perubahan ketransmisian yang cekap dan sangat pantas, yang memulihkan 73% tahap awalnya (0 fs) dalam masa 1 ps. Kaedah mudah untuk penukaran masa ke ruang telah digunakan untuk filem ini. Kami mengambil perhatian kami kepada salah satu ciri nadi femtosaat, iaitu penipisan ruang dalam arah penyebarannya. Denyutan femtosaat bagi nadi pam tunggal dan kereta api empat denyutan probe diterangi ke kawasan yang sama (diameter 10 mm) permukaan filem SQ J-agregat. Arah rasuk probe adalah normal pada permukaan filem dan rasuk pam adalah sudut serong dalam satah mendatar. Disebabkan oleh kelewatan spatial nadi pam disebabkan oleh pencahayaan dalam sudut serong kepada filem, empat denyutan probe dengan masa selang 1 ps (1 THz) bertemu tempat yang berasingan pada filem. Oleh kerana tindak balas pantas agregat SQ J, filem itu memilih sebahagian daripada setiap denyutan probe, yang mempunyai bentuk yang lebih sempit dalam arah mendatar berbanding dengan bulatan awal melalui perubahan transmisi filem. Empat garisan yang dipisahkan secara spatial telah diperhatikan oleh kamera CCD untuk imej kereta api nadi probe yang dihantar. Keputusan ini mencadangkan bahawa masa tindak balas filem agregat SQ J, yang menentukan lebar mendatar setiap baris, cukup untuk penyahmultipleksan isyarat optik 1 THz.

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.
