| Abstract: |
A new nanometer sized optical device dividing a beam of multi-wavelength light into constituent spectral wavelengths based on ZnO nanowires arrays has been presented, inspired by the diameter dependent energy bandgap of the nanowires. The theoretical validations based on the quantum optics theory have been conducted. It is shown from the simulation results that the output optical spectrum changes upon the energy bandgap of the material, which is determined by the diameter of the wire. The intensity of the optical spectrum is modeled depending on the charge density of the material. Potential applications of the proposed device on pressure sensitive imaging are discussed. |
