Characteristic equations for the lasing Modes of infinite periodic chain of quantum wires
(IEEE, 2008-06)In this paper, we study the lasing modes of a periodic open optical resonator. The resonator is an infinite chain of active circular cylindrical quantum wires standing in tree space. Characteristic equations for the ... -
Coupled optical microcavities in one-dimensional photonic bandgap structures
(Institute of Physics Publishing, 2001)We present a detailed theoretical and experimental study of the evanescent coupled optical microcavity modes in one-dimensional photonic bandgap structures. The coupled-cavity samples are fabricated by depositing alternating ... -
Fabrication and characterization of amorphous silicon microcavities
(Bilkent University, 1999)In this thesis, planar amorphous silicon microcavities were fabricated and characterized at room temperature. Microcavities were realized by embedding the active amorphous silicon layer between distributed Bragg reflectors, ... -
Large and dynamical tuning of a chalcogenide Fabry-Perot cavity mode by temperature modulation
(Optical Society of America, 2010)Te-enriched chalcogenide glass Ge15As25Se15Te45 (GAST) is synthesized, thermo-optically characterized and used to fabricate a one dimensional photonic crystal cavity mode that is dynamically and reversibly tuned by temperature ... -
Laser action studies of π-conjugated polymer microcavities
(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 ... -
Lasing modes of infinite periodic chain of quantum wires
(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 effects in the photoluminescence of hydrogenated amorphous silicon nitride
(SPIE, 1998)Fabry-Perot microcavities are used for the alteration of photoluminescence in hydrogenated amorphous silicon nitride grown with and without ammonia. The photoluminescence is red-near-infrared for the samples grown without ... -
Stable and low ‐ threshold optical gain in CdSe/CdS quantum dots: an all ‐ colloidal frequency up ‐ converted laser
(Wiley-VCH Verlag, 2015)An all-solution processed and all-colloidal laser is demonstrated using tailored CdSe/CdS core/shell quantum dots, which exhibit highly stable and low-threshold optical gain owing to substantially suppressed non-radiative ...
