Coherent Debuts Extended C+L-Band Grisms With Unmatched Efficiency and Performance
March 15 2024 - 4:30PM
Coherent Corp. (NYSE: COHR), a leader in optical communications
components and subsystems, has introduced a groundbreaking family
of advanced, aberration-correcting, high-efficiency grisms and
transmission gratings capable of encompassing the entire extended
C+L band in a single optic. These enable construction of more
cost-effective, efficient, and compact network components that
support more communication channels, such as wavelength selective
switches (WSS) and optical channel monitors.
“Both the datacom and telecom segments are
experiencing a surge in network traffic driven by the adoption of
artificial intelligence (AI) technologies. Meeting this growth,
along with market-based pressures for reduction of cost and size,
necessitates the use of smaller, more efficient components for
network management and telemetry. These forces have driven the need
for technological innovation to combine individual C- and L-band
WSS systems with extended wavelength coverage. Coherent is the
first to develop gratings and grisms that specifically support
these needs,” said Steve Rummel, Senior Vice President, Coherent
Engineered Materials and Laser Optics.
Coherent achieves these goals through multilayer
dielectric diffraction (MLD) gratings fabricated using the same
mask projection photolithography processes employed in the
semiconductor industry.
Our innovative MLD diffraction gratings enable the
curvature and spacing of every individual grating line to be
separately and precisely controlled. This results in optics that
excel over competitive products in several important ways.
- Expanded grating functionality past
dispersion to include aberration correction and wavefront
transformation
- Exceptional efficiency up to 97%,
providing reduced power consumption and heat dissipation
- Grating design provides for higher
dispersion, which permits tighter channel spacing and improved
channel isolation
These same performance factors also combine to
deliver broader wavelength coverage over the entire extended C+L
band. The manufacturing process excellence enables Coherent to
provide this performance-enhancing product at an affordable value
to our customers.
The Coherent grism and grating platform is
qualified for a broad range of materials and groove densities and
can be readily customized to specific customer requirements.
Coherent will exhibit at OFC 2024 in San Diego, March 26-28,
booth #3412, showcasing its new products and technology for
next-generation optical communications networks and sensing.
