    • Laser action studies of π-conjugated polymer microcavities 

      Tülek, Abdullah; Vardeny, Z. V. (IEEE, 2008)
      Unidirectional laser emission was observed from φ-conjugated polymer microcavities with spiral geometry, and from microdisks containing line defects. For both type of cavities directionality contrast of the laser emission ...
    • Studies of polymer microring lasers subject to uniaxial stress 

      Tulek, A.; Vardeny, Z.V. (2007)
      The emission spectra of microring lasers fabricated from π -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 ...
