Coherent Introduces Infrared Wire-Grid Polarizers With Industry-Breakthrough Performance for Atmospheric Remote Sensing
January 25 2024 - 6:00AM
Coherent Corp. (NYSE: COHR), a leader in diffractive optics, today
announced the introduction of a family of mid-wavelength infrared
(MWIR) and long-wavelength infrared (LWIR) wire-grid polarizers
(WGPs) with industry-breakthrough performance for laser-based
atmospheric remote sensing applications.
Laser-based metrology such as for greenhouse gas monitoring is
driving the demand for high-performance optics to improve
measurement sensitivity. Coherent introduced a new family of
infrared WGPs operating in the MWIR over 3-5 µm and the LWIR over
7-14 µm, based on meta-optics wire technology that achieves a
contrast ratio of an order of magnitude greater than the
highest-performing comparable products in the industry. The
meta-optics wires of the WGPs are nanopatterned with non-oxidizing
materials, which significantly increases their reliability compared
with existing wire-grid polarizers made from aluminum, copper, or
silver materials.
“Our new family of infrared WGPs leverages our materials
expertise in infrared optics and our decades of development in
meta-optics and nanopatterning,” said Steve Rummel, Senior Vice
President, Engineered Materials and Laser Optics Business Unit.
“The WGPs designed for LWIR applications leverage our
low-absorption dielectric thin films on zinc selenide substrates
that are grown, polished, coated, and nanopatterned in-house.”
Coherent’s broad portfolio of components for laser-based remote
sensing also includes optical isolators, collimators, beam
expanders, and galvo mirrors. The MWIR polarizers are available
now, and the LWIR polarizers will be generally available in the
third quarter of calendar 2024.
Coherent leverages its diffractive optics technology platform
for a wide range of products and applications, including
state-of-the-art diffractive optical elements (DOEs) for beam
shaping in high-power laser processing, as well as volume Bragg
gratings and diffraction gratings with applications in
communications and medicine. Coherent also offers wafer-scale
all-glass DOEs based on metasurfaces, or meta-optics elements
(MOEs), that are ideal for large-volume applications such as in
consumer electronics.
Coherent will showcase its broad range of products and
innovations for sensing at Photonics West 2024 in San Francisco,
Jan. 30 to Feb. 1, Booth #4805.
