An integrated, micro-optical device for use in combination with a monomode fiber, a laser and a photodiode. A common substrate includes means for connecting the fiber, laser and photodiode to the device. A film waveguide is disposed on the substrate and presents a first beam path between the means for connecting the fiber and the means for connecting the photodiode. A refraction grating is disposed in the first beam path of the film waveguide. A second beam path is present by the film waveguide between the means for connecting the laser and the refraction grating. The refraction grating is constructed and positioned on the substrate so that the refraction grating transmits radiation coming from the fiber toward the photodiode and deflects radiation coming from the laser in the direction toward the fiber.

An integrated, micro-optical device for use in combination with a monomode fiber, a laser and a photodiode, said device comprising: a common substrate including means for connecting the fiber, laser and photodiode to said device; a film waveguide disposed on said substrate and presenting a first beam path between said means for connecting the fiber and said means for connecting the photodiode; a refraction grating disposed in the first beam path of said film waveguide, said film waveguide presenting a second beam path between said means for connecting the laser and said refraction grating; wherein said refraction grating is composed of parallel lines which are arranged in confocal elliptical arcs and which are so spaced apart to define a selective filter which transmits radiation coming from the fiber and having a first wavelength toward the photodiode, and deflects radiation coming from the laser and having a second wavelength different from the first wavelength in the direction toward the fiber.
