PR Newswire (US)
ANN ARBOR, Mich., Nov. 19 /PRNewswire-FirstCall/ -- Picometrix,
LLC, an Advanced Photonix company (NYSE Amex: API), announced that
it has been awarded patent 7,078,741 for enhanced responsivity
photodiodes and 7,468,503 for planar photodiodes by the United
States Patent and Trademark Office. These technologies can be used
individually or in combination and are deployed in the company's
high-speed optical receiver product offerings. They enable
increased responsivity, higher optical power handling capacity and
can be utilized across both the C and L wavelength bands, resulting
in industry leading optical receiver product performance for the
40G and emerging 100G telecommunication markets. Picometrix's
receiver products are incorporated into high-speed optical
communications equipment deployed in the telecommunications super
highway to support high definition video, data and voice users
worldwide. The patented photodiodes are high reliability structures
that accept light in a surface-normal geometry, achieve
industry-leading responsivity, up to 0.85 amps per watt at 40G, and
are capable of handling high optical input power. This patented
surface normal design does not require complicated semiconductor
optics to illuminate the photodiode, such as spot size converters
which are necessary for waveguide photodiodes. As a result, a
product based upon these patented photodiodes covers both the C and
L wavelength bands, is indifferent to optical polarization states,
and has superior reliability compared to mesa waveguide
photodiodes. Indifference to polarization changes in leading edge
optical communication systems is important in maintaining
transmission integrity due to the constantly changing polarization
state of the incoming light. "Proprietary, patented technology like
this helps us differentiate our products in the market," says Robin
(Rob) Risser, President and General Manager of Picometrix and CFO
of API. "Our products always meet or exceed stringent industry
performance and reliability standards and offer best in class value
to our customers. Our patented photodiodes can be used for both C
band and L band wavelengths and as a result can simplify customer
material management and reduce their inventory requirements. In
addition, indifference to polarization changes improves our product
uniformity across operating conditions which can contribute to
improved customer manufacturing yield. Our high reliability planar
photodiode structure also offers our customers the comfort of long
term reliability they have become accustomed to with lower speed
legacy systems. We look forward to continuing to provide superior
customer value through our technological leadership in high speed
optical receivers for the next generation 40G and emerging 100G
telecommunications equipment." About Advanced Photonix, Inc.
