Title:
OPTICAL TRANSMITTER AND OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2021/057096
Kind Code:
A1
Abstract:
An optical transmitter (10) and an optical module (200). The optical transmitter (10) is provided with a laser chip (114), a first metal wire (1151), a second metal wire (1152), a transistor seat (11), and a substrate (112) fixed on the transistor seat (11), signal line transmission layers (1131, 1132) being provided on the substrate (112). The laser chip (114) is connected to a signal line transmission layer (1132) corresponding to the anode thereof by means of two or more metal wires (1151, 1152), and only the first metal wire (1151) is directly welded onto a pad (1141) of the laser chip (114). The area of a solder joint formed by the first metal wire (1151) on the pad (1141) is larger than half of the area of the pad (1141). The remaining second metal wire (1152) is welded such that an upper second metal wire (1152) is welded to a first metal wire (1151) at the bottom portion thereof. As such, the number of metal wires (1151, 1152) may be increased without increasing the area of the pad (1141) of the laser chip (114). Compared with a single wire, the total diameter of the metal wires (1151, 1152) may be increased, which may thereby reduce the inductance generated during the working process of the optical module (200) thereof, and which may be beneficial in improving the high-speed photoelectric performance of the optical module (200).
