    • Conditions for observation of Rabi oscillations in an exciton-polariton system 

      Shumovsky, A. S.; Müstecaplioǧlu, Ö. E. (Elsevier BV, 1995)
      The pure quantum model describing Rabi oscillations of exciton-polaritons (EP) in a micro-cavity with finite quality is considered. It is shown that the oscillations can be observed if the cavity damping rate does not ...
    • Lasing modes of infinite periodic chain of quantum wires 

      Byelobrov, V. O.; Benson, T. M.; Sewell, P.; Altıntaş, Ayhan; Nosich, A. I. (IEEE, 2009-06-07)
      In this paper, we study the scattering and eigenvalue problems for a periodic open optical resonator that is an infinite chain of active circular cylindrical quantum wires standing in free space. The scattering problem is ...
    • Microcavity lasers on polymer materials: Boundary integral equation modeling and experiments 

      Nosich, A.I.; Smotrova, E.I.; Lebental, M.; Sukharevsky Ilya O.; Altıntaş, Ayhan (IEEE, 2015-04)
      We consider the modeling and experiments with polymer dye-doped lasers shaped as thin flat cavities, allowing one to consider them as two-dimensional (2-D) active cavities. We focus our modeling on the H-polarized ...
    • Ultralow threshold laser action from toroidal polymer microcavity 

      Tulek, A.; Akbulut, D.; Bayındır, Mehmet (American Institute of Phycsics, 2009)
      We report laser action from a toroidal microcavity coated with π-conjugated polymer. An ultralow threshold value of ∼200 pJ/pulse is achieved by free space excitation in ambient conditions. This is the lowest threshold ...
    • Ultrasensitive label-free microcavity biosensors with high selectivity 

      Özgür, Erol; Bayındır, Mehmet; Aktaş, Ozan (IEEE, 2011)
      High quality factor whispering gallery mode microresonators have been recently shown to exhibit detection sensitivity of single molecule; however, the selectivity of these sensors among different types of analytes remains ...
    • Unidirectional laser emission from π-conjugated polymer microcavities with broken symmetry 

      Tulek, A.; Vardeny, Z.V. (2007)
      We report unidirectional laser emission from π-conjugated polymer microcavities with broken symmetry geometries such as spiral and microdisk containing a "line defect," in comparison with plain microdisk cavity having ...
    • Wafer-scale arrays of high-Q silica optical microcavities 

      Ozgur E.; Huseyinoglu E.; Dana, A. (OSA - The Optical Society, 2017)
      On-chip high-Q microcavities possess significant potential in terms of integration of optical microresonators into functional optoelectronic devices that could be used in various applications, including biosensors, ...
