The feasibility of recording optical information at the nano level has been considered for a long time restricted by the wave length of light. The concept of wavelength of light in classical optics is a direct consequence of the standard solution of the Maxwell equations for purely harmonic functions. Propagating harmonic light waves in vacuum or air satisfy the required mathematical conditions imposed by the Maxwell equations; hence in classical optics the concept wavelength of light has been associated with this type of waves. Mathematically one can derive solutions of the Maxwell equations utilizing Fourier integrals and show that light generated in a volume with dimensions much smaller than the wavelength of light will have periods that are in the region called sub-wavelength region. Every oscillator, whether a mass on a spring, a violin string, or a FabryPerot cavity, has some common properties that arise from the mathematics of vibrating systems and the solutions of the differential equations that govern the vibratory motions. In this paper some common properties of vibrating system are utilized to analyze the process of light generation in nano-sized crystals. Although simple, the model illustrates the process of light generation without getting into the very complex subject of the solution of quantum resonators.
