Abstract
In a light source device for combining light waves with at least three wavelengths and outputting thus combined light waves, an optical system element and an electrical system element are formed on a semiconductor substrate, thereby eliminating the necessity of optical members such as an optical connector, and saving space to place the optical members as well as reducing arrangement spacing. In addition, the space necessary for wiring in an electrical circuit is reduced. Therefore, an integration degree of each of the elements, the optical system element and the electrical system element, is enhanced. The optical system element and the electrical system element are formed in layers on the same conductor substrate, thereby reducing the area that is required in configuring a parallel establishment of the optical system element and the electrical system element.
