Direct transmission of pictorial information in multimode optical fibers [PDF]
, 1976 The problem of coherent image transmission through a single multimode optical fiber is discussed. A scheme is presented for recovering the transmitted image after distortions brought about by the fiber modes dispersion.

All-fiber spatiotemporally mode-locked laser with multimode fiber-based filtering. [PDF]
Optics Express, 2020 We demonstrate the first all-fiber multimode spatiotemporally mode-locked laser. The oscillator generates dissipative soliton pulses at 1036 nm with 12 mW average power, 6.24 ps duration, and 24.3 MHz repetition rate.

Temperature Effects of a Multimode Biconical Fiber Coupler [PDF]
, 1986 A theoretical analysis of the temperature sensitivity of a multimode biconical fiber coupler as well as that of a multimode uniform fiber coupler has been given. The results show that a biconical coupler has some advantages over an ordinary fiber coupler
