Broadband Supercontinuum Generation in PCF, HNLF and ZBLAN Fiber with a Carbon-Nanotube-based Passively Mode-locked Erbium-doped Fiber Laser
Sivasankara Rao Yemineni, Wennjing Lai, Arokiaswami Alphones +1
We demonstrate the broadband supercontinuum (SC) generation in photonic crystal fiber (PCF), highly nonlinear fiber (HNLF) and ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) fiber with a passivel…
Fast switchable electro-optic radial polarization retarder
B. C. Lim, P. B. Phua, W. J. Lai +1
A fast, switchable electro-optic radial polarization retarder (EO-RPR) fabricated using the electro-optic ceramic PMN-PT is presented. This EO-RPR is useful for fast, switchable ge…
High power radially polarized light generated from photonic crystal segmented half-wave-plate
P. B. Phua, W. J. Lai, Y. L. Lim +4
We have generated more than 100 watts of radial polarized beam from a Yb fiber laser using a photonics crystal segmented half-wave-plate. We demonstrated the high power handling ca…
A high fidelity approximation of radial polarization conversion
P. B. Phua, W. J. Lai, Yuan Liang Lim
We report a high fidelity (>90%) approximation of radial polarization conversion using a birefringent lens. It offers the advantages of low-cost, easy fabrication, alignment robust…
Polarization Retarder with Cylindrical-Symmetry for Radially Polarized Light
P. B. Phua, W. J. Lai, Yuan Liang Lim
We demonstrate a cylindrically-symmetric polarization retarder for generating exact radially polarized light. It involves an uni-axial crystal whose crystallographic optics axis is…
Ultra-Broadband Radial Polarization Conversion based on Goos-Hanchen Shift
P. B. Phua, W. J. Lai
We demonstrate, for the first time, a scheme that generates radially-polarized light using Goos-Hanchen shift of a cylindrically symmetric Total Internal Reflection. It allows ultr…
