METAL-NANOSHELL/QUANTUM-DOT ARRAY WAVEGUIDES WITH COMPENSATED LOSS
2010 (English)In: Journal of nonlinear optical physics and materials, ISSN 0218-8635, Vol. 19, no 4, 595-601 p.Article in journal (Refereed) Published
Dispersion properties of nanoarray waveguides composed of near-field-coupled arrays of metal-clad quantum dots (QDs) are calculated. The high loss due to operation of the metal shells close to resonance is mitigated by using optical gain in the QDs. The conditions for achieving loss compensated operation are given, with realistic material parameters and neglecting inhomogeneous broadening.
