Abstract

The relative group delay of the different modes present in an all-fiber LP11 mode converter at a central wavelength of 750nm is observed using low coherence interferometric imaging. We have simultaneously measured the relative group delay and computed the intensity and the phase distribution of the modes emitted from the mode converter end face using a Fourier technique, providing unequivocal identification of the modes involved.

Schematic of the interference setup to capture the interference images using a Hamamatsu CCD camera. The abbreviations used in the figure, SC, BS, M, SMF, and PD, mean supercontinuum, beam splitter, mirror, single-mode fiber, and photodetector, respectively. The position of M3 can vary between 0 and 25 mm by computer-controlled translation stage. The near-field image of the mode converter’s output is shown in false color in the lower image. The upper image is the superposition of the light from the mode converter over the attenuated reference beam.
