Optical function device using photonic crystal, variable wavelength optical filter and variable wavelength light source |
摘要 |
A core layer contains photonic crystals formed by ferroelectric members made of a ferroelectric substance and periodically disposed along a one-dimensional direction or two-dimensional directions. Electrodes apply an electric field to the core layer. An optical function device is provided which can be made compact and can set a wavelength at high speed.
