INVESTIGATION OF OLIVE OIL AS A PHOTONIC LIQUID CRYSTAL FOR OPTICAL COMMUNICATION SYSTEM
ABSTRACT
This project introduces a prospective material for photonic laser applications. The material is olive oil which is classified as organic compound, having a good nonlinear optical properties candidate to be used in photonic applications. Many organic compounds that olive oil is contained, phospholipids, cholesterol, glycolipids, fatty acids compound which are able to behave as lyotropic liquid crystal. So, these compounds are characterized by wide photonic applications. A high purity sample of olive oil has been subjected to spectrophotometer to determine the absorption spectra. Then, the nonlinear optical properties represented by nonlinear refractive index and nonlinear absorption coefficient are determined using a highly sensitive method known as z-scan technique. z-Scan experiment was performed using a CW Nd:YAG and SHG Nd:YVO4 lasers in two parts. The first part has been done using a closed aperture placed in front of the detector to measure the nonlinear refractive index at two wavelengths (1064nm and 532nm) and versus incident powers at 1064nm. The second part was done using an open aperture to measure the nonlinear absorption coefficient at two wavelengths (1064nm and 532nm) for different incident powers at 1064nm.
