![]() | 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 | Spectral analysis of polymer microring lasers | The emission spectra of microring lasers made of p-conjugated polymer films that coat glass optical fibers are analyzed with the help of a Fourier transform. This method allows for the assignment of photopumped emission lines to integral Bessel functions and a more precise determination of the lase... | Microring lasers; pi-conjugated polymers | 2000 |

![]() | Vardeny, Zeev Valentine | Studies of polymer microring lasers subject to uniaxial stress | The emission spectra of microring lasers fabricated from ∏-conjugated polymer films casted on nylon microfibers with diameters in the range of 35-90 µm were studied upon application of uniaxial stress with strain up to ~12%. The laser emission spectra substantially change with the applied stress,... | pi-conjugated polymers; Microring lasers; Uniaxial stress; DOO-PPV | 2007 |
