We report on the first implementation of a photonic emulator platform upon which dynamic encirclement of an exceptional point can be observed. Using two polarization states, an omnipolarizer is realized based on chiral mode conversion.

We demonstrate a few-mode erbium-doped fiber amplifier employing a mode-selective photonic lantern for controlling the modal content of the pump light. Amplification of six spatial modes in a 5 m long erbium-doped fiber to x223C;6.2x2009;x2009;dBm av

We report an antiresonant hollow core fiber formed of 7 non-touching capillaries with inner tubes. The fiber has a core diameter of ∼33μm and a core wall of ∼780nm of thickness. We demonstrate robust single mode operation at 1064nm and broad tra

We observe efficient supercontinuum generation that extends into the visible spectral range by pumping a low differential mode group delay graded index multimode fiber in the normal dispersion regime. For a 28.5 m long fiber, the generated spectrum s

We demonstrate over two octaves supercontinuum generation in a graded index multimode fiber using a picosecond microchip laser at 1064 nm. Enhanced visible supercontinuum is obtained in a tunable fashion based on initial launching conditions.
