Abstract
PURPOSE:To exhibit effects in various optical circuit systems by simplifying the constitution and eliminating loss, by integrating focusing microlens and grating. CONSTITUTION:When lights of wavelengths lambda1 and lambda2 enter an optical fiber 1, they pass through a focusing microlens 4, and are reflected at different reflection angles by a reflecting film 6. The reflected lights are again focused by the focusing microlens 4, and the light of wavelength lambda1 enters, for instance, an optical fiber 2, and the light of wavelength lambda2 enters an optical fiber 3, so that they may be picked up independently. Or, contrarily, when the light of wavelength lambda1 is made to enter the optical fiber 2 and the light of wavelength lambda2 is made to enter the optical fiber 3, a mixture of lights of wavelengths lambda1 and lambda2 may be picked up from the optical fiber 1.
