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.

Description

technical field [0001] The present invention relates to, for example, a light source device suitable for a small projector. Background technique [0002] In a projector that displays color images by projecting light in the R wavelength region, G wavelength region, and B wavelength region on a screen, it is necessary to project the light in each wavelength region to one point in order to form a color image. As a configuration for projecting light in each wavelength range to one point, a technique is known in which light in each wavelength range is scanned by a mirror mechanism using a MEMS (Micro Electro Mechanical System). [0003] This structure has the following problems: when the light of each wavelength region integrated in the horizontal direction is scanned by the mirror, the timing of projecting the light of each wavelength region is shifted, and the scanning angle range of each wavelength region is different. [0004] Patent Document 1 is known as a prior art for so...
