Optical Fibres with Organic Crystalline Cores
TL;DR: In this paper, it was shown that, using extremely narrow linewidths (< 1 MHz), near-quantum noise limited detection is possible using all optical systems which do not have the speed and bandwidth limitations of electronic components.
Journal ArticleDOI
Static and frequency dependent polarizabilities and hyperpolarizabilities of h2sn
TL;DR: In this paper, the structure-polarization relationship in a series of polysulfanes, H2Sn, was investigated and the effect of conformational changes of π−conjugated systems on their hyperpolarizabities was investigated.
Journal ArticleDOI
Optical Limiting Studies on Chalcone Doped PMMA Polymer Film
TL;DR: An organic nonlinear optical (NLO) material (2 E )-1-(3-chlorophenyl)-3-(3,4-dimethoxyphenyl)prop-2-en-1-one (CPDP) with molecular formula C 17 H 15 ClO 3 has been synthesized and crystallised in methanol solution.

TL;DR: 1H and 13C NMR spectra of chalcone (trans‐benzylideneacetophenone) and 54 4,4′‐substituted chalcones were studied and the substituent constants were calculated by the least‐squares method.
Journal ArticleDOI
Measurement of second‐harmonic generation from colored powders
TL;DR: In this article, the second-harmonic generation with evanescent wave technique was used to measure the efficiency of an organic colored powder that absorbs the secondharmonic wave, and it was compared to the electro-optic coefficient.
