摘要： An optical device for optically multiplexing or demultiplexing light of different predetermined wavelengths is provided, the optical device comprising at least one first waveguide (11) and at least one second waveguide (12) formed on a substrate (10), wherein the at least one first waveguide and the at least one second waveguide intersect at an intersection, comprising a diffraction grating structure (13) formed at the intersection. There exists a first wavelength or wavelength band travelling within the first waveguide (11) exciting the grating structure and being diffracted an angle corresponding to an outcoupling direction and there exists a second wavelength or wavelength band, different from the first wavelength or wavelength band, travelling within the second waveguide (12) exciting the grating structure and being diffracted at an angle corresponding to the same outcoupling direction. The two radiation beams comprising radiation of two different wavelengths or wavelength bands are spatially separated into the optical waveguides (11 and 12) or combined into single outcoupling direction, e.g. into a single optical element, e.g. a single optical fiber (21). An optical device may be used in local access communications such as fiber to the home, office or curb applications.

The hybrid laser (100) furthermore comprises a first optical waveguide (112) and optical laser components (114) comprising reflectors in the optical passive material (110). The first optical waveguide (112) is adapted for coupling out radiation from the hybrid laser. The laser also comprises a second optical waveguide (122) defined in the optical active material (120).

The second optical waveguide (122) thereby is positioned at least partly over the first optical waveguide (112) so that an evanescent coupling interface is defined between the second optical waveguide (122) and the first optical waveguide (112) and the evanescent coupling interface is positioned within the laser cavity.
