Title (EN) VARIABLE WAVELENGTH LIGHT SOURCE
(FR) SOURCE LUMINEUSE A LONGUEUR D'ONDE VARIABLE
Abstract: front page image
(EN)If an external force is exerted on a plastic photonic crystal by a piezoelectric device (3), the photonic crystal (2) deforms and the photonic band gap easily varies. As the photonic band gap varies, the passage of light of specific wavelength is limited. As a result, light of desired wavelength is sufficiently varied and outputted from the photonic crystal (2), and the light is taken out from an output window (6) to the outside. The scale of the variable wavelength light source is small since a plastic photonic crystal (2) for varying wavelength sufficiently even though the crystal is small is used and the light source and photonic crystal are accommodated in a unit.
(FR)Si une force externe est exercée sur un cristal photonique plastique par un dispositif piézoélectrique (3), le cristal photonique (2) se déforme et la largeur de bande interdite photonique varie facilement. Comme la largeur de bande interdite photonique varie, le passage de lumière de longueur d'onde souhaitée est limitée. Il en résulte que la lumière de longueur d'onde souhaitée varie suffisamment et sort du cristal photonique (2), et la lumière prélevée d'une fenêtre de sortie (6) sort vers l'extérieur. La source lumineuse à longueur d'onde variable est à une petite échelle puisqu'on utilise un cristal photonique plastique (2) offrant une variation suffisante même si le cristal est petit et la source lumineuse et le cristal photonique sont logés dans une unité.
