Latest Patents
One of Itoh's latest patents is a variable wavelength light source. This invention utilizes a piezoelectric element that applies an external force to a plastic photonic crystal, causing it to deform. As the photonic crystal deforms, the photonic band gap changes, which limits the transmission of light at specific wavelengths. This allows for the output of light with a desired wavelength, achieved through sufficient tuning and extraction via an output window. The innovation emphasizes the use of a small plastic photonic crystal that can achieve significant wavelength tuning while being compact.
Another significant patent is an optical device that incorporates a photonic crystal with plasticity. This device is created by arranging microspheres of silica, barium titanate, or air bubbles within a gel substance. When an external force is applied, the photonic crystal deforms, leading to changes in the photonic band gap. Consequently, the passage of light at specific wavelengths is restricted, allowing for the output of light at a desired wavelength. This invention enables easy variation of the wavelength through external force.
