Hamamatsu Photonics has developed an APD array integrated with a self-bias generator to help reduce the cost of industrial LiDAR modules

Gain Stabilized Si APD S16430-01CR

At Hamamatsu Photonics, we have successfully developed an avalanche photodiode (APD) array called the "Gain Stabilized Si APD S16430-01CR" for industrial LiDAR(*1) use. This APD array was integrated with a self-bias generator (SBG)(*2) by harnessing our unique advanced opto-semiconductor manufacturing technology. Since the SBG stabilizes the optical signal multiplication factor, a microcontroller and temperature sensor are no longer needed to adjust the multiplication factor to match changes in temperature. Another benefit is that the transimpedance amplifier (TIA) in the signal processing circuit is built into the same package to further reduce the cost of LiDAR modules for automated guided vehicles. Samples of this APD array will be available to LiDAR module manufacturers from the end of October, with mass production scheduled to begin in April 2023.


*1. LiDAR: Light Detection and Ranging. LiDAR is a remote sensing technology in which the distance of a remote object is measured by irradiating a laser beam onto the target object and detecting the reflected light with an optical sensor.

*2. SBG:    A device to stabilize the optical signal multiplication factor.
