Effect of Al3+ ions on the optical quality, growth rate, shape, and structure of potassium dihydrogen phosphate (KDP) crystal was investigated. Growth method was based on the “point seed” method in a solution with optimum concentration, following spontaneous growth at room temperature. FTIR spectrum showed neutralization of O-H group in KDP crystal by Al3+ ions. UV-Visible spectrum of the cryst...

A photonic crystal biosensor based on nano-resonator is presented in this paper. The nano-resonator is constructed in the middle of structure and is surrounded by two waveguides. The resonator is formed by reducing the size of air holes. In order to better optical coupling between the waveguides and resonator, two limited waveguide are used. By binding the molecular biological to the sensing ho...
