We demonstrate a simple method for generating high-speed pulse trains from a relatively low-speed pulse source by spectral filtering using a high-finesse fibre Fabry-Pérot interferometer. Reasonably stable 40 GHz and 100 GHz pulse trains are obtained at 1550 nm from a 10 GHz mode-locked fibre ring laser.

Keywords: optical pulses, repetition rate multiplication, spectral filtering, ultrafast technology

Анотація. Запропоновано простий метод генерації високошвидкісних серій імпульсів від відносно низькошвидкісного імпульсного джерела шляхом спектрального фільтрування з використанням високодобротного волоконного інтерферометра Фабрі-Перо. Отримано стабільні серії імпульсів 40 ГГц і 100 ГГц з довжиною хвилі 1550 нм від 10 ГГц-волоконного кільцевого лазера з синхронізацією мод.
