    摘要: 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.

    摘要: For statically driving a liquid-crystal optical-modulation device, an alternating electric field produced by a drive signal is applied to a liquid crystal included therein. In a first period in which the alternating electric field has a first polarity, the drive signal is pulse-width modulated based on a first ON-voltage and a first OFF-voltage. In a second period in which the alternating electric field has a second polarity, the drive signal is pulse-width modulated based on a second ON-voltage and a second OFF-voltage.
