Optical rotation in a medium, which is typically small, can be enhanced by harnessing spin-orbit interaction in fiber modes. Here the authors use this effect to develop a fiber-based wavelength-measurement technique with high resolution.

We present a high resolution optical rotary dispersion spectrometer that can detect spectral bandwidth with high sensitivity (< 1 pm) by exploiting the induced optical activity of OAM fiber modes.

Optical rotation, a form of optical activity, is a phenomenon employed in various metrological applications and industries including chemical, food, and pharmaceutical. In naturally-occurring, as well as structured media, the integrated effect is, ho

We report stimulated Brillouin scattering (SBS) measurements in orbital angular momentum (OAM) carrying modes of an optical fiber. The additional degree of freedom afforded by angular momentum selectivity leads to new possibilities to control SBS gai

We experimentally demonstrate that pure OAM fiber modes are highly robust to out-of-plane bend perturbations in contrast to their vector counterparts (HE/EH) that mix completely, because geometric (Pancharatnam) phase accumulation varies with OAM con

We demonstrate a novel intermodal four-wave mixing process by dividing a pump at 1047nm between the LP 0,4 and LP 0,5 fiber modes, leading to simultaneously broadband (28nm at 1550nm) and wideband (∼1 octave) spontaneous parametric gain.

We seed a unique, broad-gain-bandwidth (60nm at 1550nm) intermodal four-wave mixing process yielding 10kW-peak-power pulses tunable from 786–795nm, resulting in the first power-scalable all-fiber tunable source in the spectral range of the ubiquito

Nonlinear frequency generation of light-carrying orbital angular momentum (OAM), which facilitates realization of on-demand, frequency-diverse optical vortices, would have utility in fields such as super-resolution microscopy, space-division multiple
