Description

Technical Field

[0002] In the fields of microelectronics and optoelectronics, continuous technological advancements and growing demand for product miniaturization are placing higher demands on component size, performance, and integration. As key components in modern optical systems, miniature RGB lasers are widely used in communications, sensing, healthcare, data storage, and other fields. Their performance stability and service life depend heavily on effective heat dissipation mechanisms and compact structural designs.

[0003] Traditional micro RGB laser designs often use metal or plastic substrates as support structures, with wiring connected through the side or top to achieve electrical connections. However, this design approach has several significant limitations: First, although metal substrates have good thermal conductivity, they are large, which is not conducive to component miniaturization and system integration; while plastic substrates are lightweight and easy to process, they have poor thermal conductivity and cannot meet the heat dissipation requirements of high-power lasers. Second, routing wiring on the side or top not only takes up valuable space resources, but can also increase manufacturing difficulty and cost due to the complex wiring layout, while also affecting overall electromagnetic compatibility.

[0004] In order to overcome the above shortcomings, the industry has begun to explore new substrates and innovative circuit layout methods. Utility Model Content
