Abstract

Одномодовий волокннооптичний хвилевід з керованою дисперсією містить область скляної серцевини. Хвилевід має повну дисперсію, що змінюється. Знак міняється від позитивного до негативного й від негативного до позитивного в попередньо заданому діапазоні довжин хвиль. Повна дисперсія, що змінюється, включає першу повну дисперсію Di й другу повну дисперсію Dj. Амплітуда кожної з них лежить у діапазоні приблизно від 0,5 до 20 пс/нм/км у попередньо заданому діапазоні довжин хвиль, а довжини хвиль цього заздалегідь заданого діапазону перевищують приблизно 1480 нм.
