Fiber-based pulse shaping is a topic of current research for any application scenario requiring robust, alignment-free all-fiber systems. However, the spatial domain, which could enable a spatial degree of freedom in fiber sensing applications like l

Transverse modes in optical fibers have gained increasing interest in the recent years. For the measurement of the modal amplitude and modal phase in a fiber, several techniques exist examining the spatial distribution of the light exiting the fiber

We present an inline measurement technique for the phase difference between two transverse fiber modes. This technique proves to be well suited for direct measurement of an all-optically changed phase difference between two transverse modes of picose

We present a concept using intermodal cross-phase modulation to enable all-optical temporal, spatial, and spatio-temporal pulse shaping inside a few-mode fiber. The pulse shaping is achieved by all-optically tuning a fiber-based, inline Mach–Zehnde

With the development of new fiber types, such as few-mode graded-index fibers, transverse modes in optical fibers have gained increasing interest in the recent years. As it became easier to address individual modes, transverse modes could be exploite

We demonstrate ultrafast, all-optical conversion of transverse modes in a novel dual-wavelength setup. Mode conversion of picosecond probe pulses by optically induced transient long-period gratings using sub-picosecond control pulses is directly obse

We demonstrate the potential of all-optical switches in integrated waveguides based on intermodal cross-phase modulation between transverse modes. For this purpose, the differential phase between two transverse modes of a probe beam was altered by cr

We report on experimental conversion of picosecond probe pulses from the fundamental mode (LP01) to the next higher-order mode (LP11) by optically induced transient long-period gratings in a graded-index fiber using subpicosecond control pulses. In c

We demonstrate the potential of birefringence-based, all-optical, ultrafast conversion between the transverse modes in integrated optical waveguides by modelling the conversion process by numerically solving the multi-mode coupled nonlinear Schroedin

We present the experimental realization of transverse mode conversion in an optical fiber via an optically induced long-period grating by employing a setup with co-propagating femtosecond write and probe laser pulses.
