II-VI Incorporated Introduces High-Efficiency Multifunctional Metalenses for Ultracompact Optical Sensors
June 23 2021 - 7:00AM
II‐VI Incorporated (Nasdaq: IIVI), a leading provider of
wafer-level diffractive optics, today announced the introduction of
high-efficiency multifunctional metalenses based on a II-VI
proprietary platform that enables ultracompact optical sensors for
a broad set of applications, including in consumer electronics,
automotive, life sciences, and industrial markets.
Optical sensors are increasingly embedded in diverse products
such as smartphones, automotive vehicles, medical diagnostics, and
laser processing heads, driving the demand for more efficient
miniature optical subsystems that are compact, reliable, and
manufacturable at scale. II-VI’s new metalenses
are diffractive optical elements (DOEs) that are flat and can
achieve multiple optical functions with extremely high efficiency
on a single surface for a broad range of wavelengths. In one
implementation, II-VI’s metalens both collimates and splits the
light from vertical cavity surface-emitting lasers (VCSELs) into a
highly uniform grid of thousands of infrared beams that are
projected on the scene. Optical sensors reference these grids to
accurately construct the scene in three dimensions.
“The high reliability of our glass-based DOEs are field-proven,
as part of our optical communications products that we have been
shipping in volume for years,” said Dr. Sanjai Parthasarathi, Chief
Marketing Officer, II-VI Incorporated. “Furthermore, our metalenses
can be utilized with our VCSELs to enable differentiated
ultracompact 3D sensing cameras, spurring broader adoption in
consumer electronics and automotive.”
II-VI’s broad portfolio of products for sensing includes
infrared VCSEL chips, including multi-junction designs, from one to
hundreds of emitters. II-VI VCSEL arrays are designed for low-cost
non-hermetic packaging and can be reliably and cost-effectively
scaled in total power by increasing the number of emitters per
chip. II-VI VCSEL arrays are available as chips or integrated with
DOEs in surface-mountable modules. II-VI’s DOEs include lenses,
micro-lens arrays, diffusers, and splitters. II-VI also offers
thin-film filters that are used to improve the signal-to-noise
ratio of image sensor arrays.
