Abstract:
A new technique is presented for observing the modal structure of a multimode fiber as a function of time. The times of arrival of the modes are recorded with a temporal resolution of 0.03 psec, together with the mode patterns. The experiments were made on a fiber carrying less than 10 modes, and the length of the fiber under test was 1.5m.
