Abstract

Способ обработки оптического импульсного сигнала, причем обработка включает одну или несколько операций, к которым относятся: формирование импульсов, обработка нелинейности и мониторинг. Способ реализуют с помощью устройства, выполненного с возможностью осуществления каскадной генерации второй гармоники относительно конкретной основной гармоники, при этом способ заключается в том, что в устройстве выбирают конкретную длину оптического пути, пригодную для выполнения, по меньшей мере, одной из вышеуказанных операций над входным оптическим импульсным сигналом, переносимого на волне, длина которой определяется конкретной основной гармоникой, передают входной оптический импульсный сигнал, переносимый на волне определенной длины по выбранному оптическому пути в устройстве, получают из устройства выходной оптический импульсный сигнал на основной гармонике, который подвергся обработке нелинейности и/или формированию импульсов, и/или получают выходной оптический импульсный сигнал на второй гармонике для дальнейшего мониторинга и оценки входного оптического импульсного сигнала.
