Self developed chip high reliability detector product matrix

SAN-U Optronics: Heavy Release of Self Developed Photodiode Chips and Series Devices

Recently, SAN-U Optronics' self-developed Photodiode chip and series of devices were officially released, marking our company's promotion of domestic substitution of key optical devices in the field of optical communication. As a key link in the optical communication industry chain, PD chips are known as the "translator of optical signals", and their performance directly determines the transmission efficiency and reliability of optical communication systems. Based on the technological breakthrough of self-developed PD chips, SAN-U Optronics has launched four major product matrices: MiniPD series, tail fiber PD (adhesive/laser welding), TapPD series, and arrayed PD devices. With the dual advantages of "diversified product types+domestic chip substitution", the products are mainly used in the fields of fiber amplifiers, optical power meters, optical signal data transmission, and optical sensing.

Self developed Photodiode chip and series device product Series

① SAN-U self-developed Photodiode chip

The Photodiode self-developed chip adopts a PIN structure design, which has ultra-low dark current, high reliability, and low voltage operation characteristics. The working temperature range covers -40~+85 ℃, meeting the stable operation requirements in extreme environments.

② Mini Photodiode series

The Mini Photodiode series products have a minimum diameter of 1.2mm and are equipped with high-precision and highly reliable gas sealing technology. While the size is reduced, the devices still have high performance and reliability. Mainly used in high-speed optical communication (high-speed fiber optic transceiver modules, fiber optic amplifiers), optical sensing systems (oil well monitoring, power equipment temperature measurement, perimeter security), industrial and military, aerospace and other high-end application fields.

③ Photodiode with pigtail series

The SAN-U Optronics  PD with pigtail series products have constructed a product matrix covering multiple scenarios through process differentiation design, using two packaging processes of adhesive and laser welding to accurately match different application needs. The adhesive process relies on an automated mass production system to achieve low-cost and high-efficiency production, especially suitable for cost sensitive large-scale scenarios such as optical communication equipment; The laser welding process uses gold tin eutectic welding technology to form stable connections through intermetallic compound bonding, which can meet the strict reliability requirements of industrial applications. This product can be widely used in fields such as optical communication and fiber optic sensing.

④ The TapPD series

The TapPD series of products integrates a splitter and a detector into a compact package, enabling real-time, non-destructive sampling and monitoring of optical signals without interrupting the main optical path signal transmission, thus ensuring stable signal transmission. The products are primarily used in fiber optic communication transmitters, fiber optic amplifiers, optical power meters, medical lasers, and other fields.

⑤ The ArrayPD device series

The ArrayPD device series, through its array design, achieves higher detection efficiency and faster response speed. This product is suitable for high-end applications such as lidar and medical imaging, providing strong technical support for the development of related industries.

CORE PARAMETERS COMPARISON

After extensive testing and comparison between SAN-U's self-developed Photodiode chip and well-known foreign chips, as well as customer testing and feedback, it is found that SAN-U's chip has lower dark current compared to foreign Photodiode chips, while other parameters and performance are on par or better than those of foreign chips.

LOCALIZATION ACCELERATES SELF-CONTROL

SAN-U Optronics  has been deeply involved in the field of optoelectronics for over 20 years, with a full industrial chain layout of "chip design - packaging and testing - module application". Currently, with the accelerated construction of AI computing power centers, the accelerated layout of in-vehicle optical communication and 10-gigabit networks, the demand for optical communication devices is experiencing explosive growth. SAN-U Optronics  is precisely positioning itself to seize these market opportunities.
