![]() | Vardeny, Zeev Valentine | Plastic microring lasers on fibers and wires | Photopumped, pulsed, narrow line laser emission is demonstrated using cylindrical microcavities formed by p-conjugated polymer thin films wrapped around thin glass optical fibers and metal wires with various diameters D. A variety of cavity-dependent resonant laser mode structures were observed, whi... | Microring lasers; pi-conjugated polymers; pi-conjugated polymer thin films; Microcavities | 1998 |

![]() | Vardeny, Zeev Valentine | Lasing and stimulated emission in ∏-conjugated polymers | Recent studies of lasing and stimulated emission in luminescent -conjugated polymers performed by our group are presented. Optical properties of cylindrical high- polymer microcavities are discussed. The emission spectra of plastic microring and microdisk lasers are measured and analyzed.

![]() | Vardeny, Zeev Valentine | Unidirectional laser emission from ∏-conjugated polymer microcavities with broken symmetry | We report unidirectional laser emission from ∏-conjugated polymer microcavities with broken symmetry geometries such as spiral and microdisk containing a "line defect," in comparison with plain microdisk cavity having isotropic emission. We found that the laser emission directionality contrast ra... | pi-conjugated polymers; Unidirectional laser emission; Microcavities; DOO-PPV; Poly(dioctyloxy) phenyl vinylene | 2007 |
