Experimental realization of transverse mode conversion using optically induced transient long-period gratings
Tim Hellwig, Martin Schnack, Till Walbaum +2
We present the experimental realization of transverse mode conversion in an optical fiber via an optically induced long-period grating. The transient gratings are generated by femt…

Optically induced mode conversion in graded-index fibers using ultra-short laser pulses
Tim Hellwig, Till Walbaum, Carsten Fallnich
We propose the use of graded-index few-mode fibers for mode-conversion by long-period gratings (LPG) transiently written by ultrashort laser pulses using the optical Kerr effect. T…
