Controlling waferbow is important in order to minimize performance variations between devices on a wafer. FBH recently developed and qualified a laser patterning process on 305 nm UVB LEDs that significantly reduces waferbow.
The LISA satellite mission aims to detect and characterize gravitational waves. To achieve this, three laser interferometers will be used that require suitable metrology lasers. The FBH has developed a 1064 nm diode laser with resonant optical feedback to be used as seed laser, aiming to replace Nd:YAG NPRO lasers used so far.
LiDAR sensors have become a fast growing market segment with a broad range of applications, from automotive to robotics. The FBH has developed the required GaN-based laser drivers, delivering 100 W optical pulse peak power with pulse widths from 3-10 ns and pulse currents from 180-250 A.
