JDSU Optical Coating Improves Light Sensing in Consumer Electronics

Feb 2011
MILPITAS, Calif., Feb. 8, 2011 — New microlithography, or patterning processes, were developed for JDSU’s optical coatings to improve light sensing intelligence in a variety of consumer electronic products, the company said.

Coatings patterned with the new processes are layered onto optical sensors that allow products to sense and adjust according to ambient light conditions. End products with the new development include smart phones with lighted screens that fade out when pressed to a caller’s ear, and dashboard displays in automobiles that adjust light intensity based on external conditions.

“There is a continued need to feed computer chips with more information so that end products can better recognize and respond to what is happening in the external environment,” said Markus Bilger, product manager for Custom Optics at JDSU.

Patterned on 200-mm wafers, the optical coatings let manufacturers in the optoelectronics and imaging industries create smaller products that have more layers of functionality embedded within the coatings at lower prices.

JDSU provides communications test and measurement solutions and optical products for telecommunications service providers, cable operators, network equipment manufacturers, enterprise customers and mobile operators.

GLOSSARY
microlithography
A technique for producing micron-size structures on surfaces by using short-wavelength light or electron beams.
optoelectronics
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
