Enhancement of surface plasmons in an Ag aggregate by optical gain in a dielectric medium

Optics Letters (2006)

M. A. Noginov Guohua Zhu M. Bahoura John A. Adegoke Cephas E. Small

We have observed the compensation of loss in a metal by a gain in a dielectric medium in the mixture of an Ag aggregate and a Rhodamine 6G dye. The demonstrated sixfold enhancement of the Rayleigh scattering is the evidence of the enhancement of the surface-plasmon resonance. The reported experimental observation facilitates many applications of nanoplasmonics.

Effect of strong coupling on Stokes shift in dye molecules

Conference on Lasers and Electro-Optics (2016)

E. K. Tanyi Hannah Thuman S. Koutsares N.J. Brown M. A. Noginov

We found that strong coupling with the cavity can increase Stokes shift of the dye molecules. The experimental finding is qualitatively explained with the simple model based on the splitting of the excited state parabola.

New Promising Low Sc3+ Content Garnet YSAG:Cr3+, Ho3+, Tm3+ for 2-μm Lasers

Advanced Solid-State Lasers (1992)

A. I. Feodorov G. B. Loutts M. A. Noginov И. А. Щербаков Vitaly Smirnov

The new low scandium content (20%) garnet YSAG:Cr3+,Ho3+,Tm3+ was grown with Czochralsky technique. It is of good optical quality, combines the advantages of YAG and YSGG crystals, demonstrates good spectroscopic and lasing properties and therefore is a promising active medium for 2 μm-lasers.

Modification of electric and magnetic dipole emission in anisotropic plasmonic systems

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2012)

Н. Ногинова Rabia Hussain M. A. Noginov Jarrett H. Vella Augustine Urbas

Spontaneous emission of a dipole can be significantly modified in metamaterials, providing opportunities to engineer emission rates, yields, spectra, and angular patterns. To better understand specifics of such modifications for electric and magnetic emitters, we study luminescence of Eu³⁺ ions placed in a close vicinity of arrays of gold nanostrips. The luminescence is strongly polarized, with the preferable polarization parallel to the direction of strips. Polarization patterns and angular distributions of radiation depend on wavelength, and are different for electric and magnetic dipole transitions. The results are discussed in terms of different coupling of emitters with radiative and high-loss modes.

Two-step upconversion luminescence in Yb:Tb:YSGG crystal

Journal of the Optical Society of America B (1996)

M. A. Noginov P. Venkateswarlu M. Mahdi

Multiline upconversion luminescence ranging from 375 to 635 nm was studied in Yb:Tb:YSGG crystal, a possible candidate for a tunable upconversion laser material. This luminescence was attributed to the transitions starting from the 5D3 and 5D4 excited levels of Tb. Two sequential steps in the upconversion were determined: at the first step Yb–Tb cooperative upconversion and cooperative absorption populate level 5D4, and at the second step interaction of excited Yb and Tb (in the 5D4 state) ions populates level 5D3. At 500-mW Ti:sapphire pumping, the excited-state concentration of Tb ions exceeded 2% of Yb excited-state concentration.
