Title:
LASER LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/123659
Kind Code:
A1
Abstract:
In the present invention, lead pins (2a, 2b) pass through a metal stem (1). A support block (3) is mounted atop the metal stem (1). A dielectric substrate (4) is mounted on a lateral surface of the support block (3). Signal lines (5a, 5b) are formed on the dielectric substrate (4). One end of the signal lines (5a, 5b) is connected to the lead pins (2a, 2b). A semiconductor light modulation element (6) is mounted on the dielectric substrate (4). Conductive wires (8a, 8b) connect the other end of the signal lines (5a, 5b) to the semiconductor light modulation element (6). The semiconductor light modulation element (6) has a plurality of light modulators (6b, 6c) that are separated from each other.
