Applied Optoelectronics Announces Narrow Linewidth Laser for automotive LIDAR
March 30 2020 - 7:00AM
Applied Optoelectronics, Inc. (Nasdaq: AAOI), a leading provider of
fiber-optic access network products for the internet datacenter,
cable broadband, telecom and fiber-to-the-home (FTTH) markets,
today announced the release of a high power and narrow linewidth
laser specifically designed for Light Detection and Ranging (LIDAR)
applications, particularly for automotive use.
Current automotive LIDAR systems are based on near infrared
lasers, however these lasers are not eye safe and therefore are
limited in terms of emitted power. This power limitation, in
turn, restricts the effective sensing range of the LIDAR
system. AOI’s laser operates at longer wavelengths near
1550-nm where eye-safe emission limits are much higher and
therefore detection distances are longer, making them better suited
for real-world automotive sensors.
Combining high optical output power with narrow linewidth
further increases the detection range of a LIDAR system by
increasing the coherence length of the laser output compared to
similar lasers with wider linewidth. The lasers are intended
to be used in Frequency-Modulated Continuous Wave (FMCW) LIDAR
systems, which have better noise rejection compared to the more
common amplitude modulated LIDAR systems available today.
“AOI’s expertise in semiconductor laser design and production
has enabled us to offer this innovative narrow-linewidth laser,”
said Dr. Fred Chang, AOI’s Senior VP and GM. “The current
automotive LIDAR systems have limitations imposed by the available
lasers, and AOI’s new 1550-nm eye-safe laser will enable advanced
FMCW LIDAR systems with improved detection range and accuracy,
which are critical to advanced autonomous vehicle technology.”
The new lasers are available for customer sampling
immediately.
