Abstract
We present a high-power DFB technology that meets the performance and volume demands of consumer automotive applications. Our DFB design is hardened and intended for use at extreme environmental conditions and operates at peak current density of 8 kA/cm2 - approximately 4 times higher than more conventional DFB lasers intended for use in telecommunication and sensing applications. We demonstrate that the risks associated with placing these components into high volume production with high yield can be managed through careful control of the laser design and manufacturing processes. To date, we show >90% of our DFB lasers fall within our control limits as defined by three sigma of the mean. This is the first high-power DFB laser suitable for widespread deployment into the consumer automotive market space.
