STERLING, Va., Nov. 18 /PRNewswire/ -- 4Wave Inc. has been issued a patent
on its innovative multi-filter chip, a product that will enable deployment of
10-Gigabit Ethernet in metropolitan networks.
U.S. Patent No. 6,819,871, titled "Multi-Channel Optical Filter and
Multiplexer Formed From Stacks of Thin-Film Layers," is the 13th issued patent
in the company's rapidly expanding intellectual property portfolio.
This portfolio covers both the product itself -- the multi-filter chip --
and the technology used to manufacture it. This technology, Biased-Target
Deposition (BTD), is a hybrid between ion beam deposition and conventional
sputter deposition that combines the best of each technique and is uniquely
suited to demanding applications requiring atomically engineered thin films.
4Wave has two additional patents pending.
"This latest patent is a major achievement for 4Wave as we move forward in
developing the first prototypes of the multi-filter chip and look ahead to our
commercialization strategy," said 4Wave President Sami Antrazi.
Compared to today's products, 4Wave's multi-filter chip will be 250 times
smaller, be far more reliable and fully compliant with IEEE standards for 10-
Gigabit Ethernet transceivers.
4Wave is currently developing prototypes of the multi-filter chip with
support from a $2 million grant from the National Institute of Standards and
Technology's Advanced Technology Program.
A key advantage of 4Wave's multi-filter chip is that it makes it possible
to deploy 10-Gigabit Ethernet on already installed multi-mode fiber in local
area networks, wide area networks, and metro access. It eliminates the need
to install expensive, cumbersome electronics or to replace existing multi-mode
fiber, offering a unique, cost-effective solution for the next generation of
