Title:
OPTICAL SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/079510
Kind Code:
A1
Abstract:
Provided is an optical semiconductor device in which a first conductive pattern (13) is provided to the upper surface of a sub-mount (7). A GND pattern (9) is provided to the lower surface side of the sub-mount (7). A lower surface electrode (21) of a capacitor (3) is joined to the first conductive pattern (13) by solder (22). An upper surface electrode (23) of the capacitor (3) is connected to a light-emitting element (2). A termination resistor (4) is connected to the first conductive pattern (13). The first conductive pattern (13) includes a protruding section (25) that protrudes from the capacitor (3) in a planar view. The width of the protruding section (25) is narrower than the width of the capacitor (3).
