The main parameters of laser diode, such as output wavelength, threshold current, and service life, are all significantly affected by temperature. This temperature sensitivity is especially prominent in high-speed, long-distance communication applications. To reduce the impact of temperature on laser diode, manufacturers will choose to install EXSENSE gold electrode NTC chips in their designs for temperature monitoring, ensuring that laser diode operates within a stable temperature range.

1. High Accuracy Ensures Precise Temperature Data

During operation of laser diode, even minor temperature changes may affect its performance. The EXSENSE ±1% high-accuracy gold termination NTC chip can accurately collect temperature data during laser diode operation, providing the laser diode TEC with precise temperature feedback. This allows for efficient temperature control, preventing the fluctuations in parameters of laser diode wavelength, power, etc. due to temperature deviations, thus ensuring the stable operation of the laser diode.

2. Small Dimension Meets the Miniaturization Requirement of Laser Diode

In recent years, applications such as optical transceiver, LiDAR, and gas sensor have increasingly demanded the miniaturization of laser diode. The size of EXSENSE gold termination NTC chip can reach 0.21mm × 0.21mm, which makes it easy to install within the limited space inside a laser diode to monitor temperature. The EXSENSE bare chip does not occupy much installation space, helping to improve the integration of the laser diode.

3. Great Consistency Ensures Efficient Operation

EXSENSE laser diode NTC chip is made of gold electrodes and self-developed semiconductor ceramic materials, providing excellent electrical performance. This feature enables the NTC to perform temperature monitoring effectively even under complex operating conditions of laser diode, ensuring the accuracy of temperature data acquisition.

As a key temperature-sensing component in laser diode, the importance of EXSENSE bare chip is self-evident. The high temperature sensitivity of EXSENSE gold termination NTC chip allows laser diode to maintain a stable wavelength and ensures long-term operational reliability, extending its service life. Therefore, whether in optical transceiver for high-speed data transmission, LiDAR detection systems for autonomous driving, or gas sensor in industrial/household gas detector, EXSENSE gold termination NTC chip provides a solid temperature protection foundation for laser diode, helping it achieve better operational efficiency and longer life cycle in various application scenarios.
