Using a 75m long HF with an effective are of 2.85 Вµm2 we obtained internal gain of over 42dB for the amplifier and 11dB extinction ratio for the modulator. Raman spectroscopy is based on the Raman effect discovery by C.V. Raman in 1928 where the measurement of the wavelength and intensity of inelastically scattered light from molecules or crystal lattices have been done.

process leading to this inelastic scatter is termed the Raman effect. Raman scattering can occur with a change in vibrational, rotational or electronic energy of a molecule. If the scattering is elastic, the process is called Rayleigh scattering. If it’s not elastic, the process is called Raman scattering. Raman scattering (or the Raman effect) was discovered in 1928 by V. C. Raman who won The Raman spectra of methyl methacrylate and similar compounds have been investigated and interpreted. The changes in the molecular constitution on polymerization indicate the disappearance of a = C – – H H linkage and the like disappearance of the C=C linkage.
