Discovery Semiconductors, worldwide leader in the manufacture and distribution of 10 & 40 Gigabit fiber optic receivers, announced today that it has received approval for a key patent by the Canadian Intellectual Property Office entitled 'Method and Apparatus for Monolithic Optoelectronic Circuit Using Selective Epitaxy'. The patent, number 2,225,930, was applied for on 6/26/1996 and granted on 3/27/2001.
In this invention, a monolithic optoelectronic integrated circuit (OEIC) is formed using an InGaAs photodiode and a silicon CMOS readout circuitry permitting the growing of high-speed infrared detectors directly on integrated circuits such as amplifiers. This close integration is vitally important to obtaining superior performance in 10 and 40 Gigabit/sec modules as it minimizes path length and parasitic impedances.
According to Discovery CEO and company founder, Abhay Joshi, "Discovery Semiconductors plans to utilize this monolithic technology for advancing its line of state-of-the-art Optical Receivers. The invention allows the use of mature silicon CMOS processing technology to fabricate the OEICs and thereby in the future achieve significant cost saving as compared to GaAs and even SiGe processing. As silicon CMOS tops 10 Gb bandwidth in year 2001, it will automatically replace not only GaAs but even SiGe as the material of choice. Also, the silicon CMOS speed of 10 Gb in 2001 will keep on increasing for the next decade, thereby increasing the value of the patent."
Joshi went on to say, "Since Canada is home to several telecommunication and fiber optic companies and a U.S. patent does not provide Intellectual Property (IP) protection in Canada, we decided to file for the Canadian patent. In doing so, the company will protect its IP both in the USA and Canada. The U.S. patent covering this technique was already granted back in 1997."
The awarded patent will be valid for several years, assuring Discovery's technological edge in the marketplace for 2 decades.
About Discovery Semiconductors, Inc.
Discovery is a leading designer, manufacturer and marketer of ultra-wide bandwidth fiber-optic photodiodes and optical receivers for optical networking, communications and aerospace markets. A privately held firm, it was founded in 1993 for developing opto-electronic detection technology for sensing and communications applications. Based in Ewing, NJ (USA), the company has also achieved certification as ISO9001:2000 compliant.
The winner of a number of research contracts from NASA, the US Air Force and the US Army, the company has developed unique technology for sensor arrays and ultra-wide bandwidth photodiode detectors. The company has several patents granted or pending on its technology. It has leveraged the resulting expertise in RF microwave detection and packaging to make its market leading commercial products. Since 1998, it has expanded its distribution globally, serving over 400 organizations in the telecommunications, data communications and aerospace industries. These achievements resulted in 411% growth from 1995 to 1999, earning a place on the Deloitte and Touche list of New Jersey's Fast 50 companies in 2000. The company received the same honor again in 2001 with a growth of 400% from 1996 to 2000.
