| 英文摘要 | PURPOSE:To attain a high industrial productivity by a method wherein a plurality of photo elements provided in a single substrate is intercommunicated in an outer wave path so that laser coupling of the photo elements with the outer wave path may be properly established. CONSTITUTION:A laser-emitting element 14 and laser-receiving element 13 are formed on a semiconductor substrate The element 14 is of a distributed feedback type, with the surface of diffraction lattice 4 provided on the substrate 1 facing an activation layer 3 inside the element 14. The element 13 is again of the distributed feedback type, incorporating a lattice surface 4 provided within a mode selecting feature within. An end face 24 of the element 13 is a crystal cleavage face wherefrom a laser beam is emitted. Between the elements 14, 13, an outer wave path 9 is provided, not furnished with a diffraction lattice face, for the establishment of optical coupling. The beam outputted by the element 14 is led through a wave path 9 to be guided into the element 13 and the yielded power is monitored there. With the circuit being constructed as such, the growth is effected with ease on crystals between the wave paths inside the elements 14, 13 constituting the outer wave path 9, ensuring operation even in the presence of coupling inefficiency. This results in an excellent industrial productivity. |
