Resonance modulated amplified emission from CdSSe nanoribbons

We present evidence of amplified emission mediated by surface plasmon polaritons (SPPs) from a CdS0.2Se0.8 nanoribbon (NR) supported on a gold-coated silicon substrate. Room temperature amplified emission is observed from the nanoribbon above excitation irradiances ~ 25 W/cm(2) when it is supported on the gold coated silicon substrate. The nanoribbon is shown to act as a resonator cavity, leadi...

Characteristics of Dual Amplified Spontaneous Emission from MEH-PPV Solutions

We report the observations of dual wavelength amplified spontaneous emission from the solutions of a conjugated polymer poly [2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (MEH-PPV) in Tetrahydrofuran and 1, 2 Dichlorobenzene. We have prepared MEH-PPV using a modified procedure and purified several times in each step, the material offers low molecular weight, low polydispersity index an...

Amplified Spontaneous Emission'

We review the coherence properties of the self-amplified spontaneous emission (SASE). Temporally, SASE is similar to the spontaneous undulator radiation except that the spectral bandwidth is about ten times narrower compared with typical undulator radiation. The situation is quite different in the transverse dimension, where SASE is fully coherent. INTRODUCTION Several laboratories are pursuing...

Resonance-Amplified Diffraction Sensors

The need to improve sensing technology for widespread application in everyday life is fueling the development of diffraction-based sensing, an optical sensing technique. Selectivity and sensitivity issues must first be resolved. Both selectivity and sensitivity can be increased by using resonance conditions — that is, using a probe wavelength where the system absorbs. The resonance effects are ...
