Light Management Group Inc. Develops Radically New Fiber-Optic Compression Technology
BURLINGTON, Ontario--(BUSINESS WIRE)--April 25, 2000--Light Management Group, Inc. (OTCBB: LMGR) is pleased to announce that it has filed for a United States patent for an Information Compressor for Fiber-Optic Lines. This radical new technology, developed by LMGR Chief Engineer Gennadii Ivtsenkov, Ph.D., can generate wavelength division multiplexed (WDM) signals with increased channel density.
One of the main challenges today in fiber optic communication technology is the compression of communication - providing multi-channel communication in a single fiber optic line. The single wavelength, fiber optic line can now carry 1 to 5 Gigabits per second of information. Using communication compressing technology, such as Wavelength Division Multiplexing devices (WDM), it is possible to multiply the capacity of the line. This is very important for Optical Access, Metro, Regional and Backbone Networks, which are being implemented now.
LMGR's invention is An Information Compressor for Fiber-Optic Lines. It is a new approach to Wavelength Division Multiplexed technology. The existing WDM systems are restricted in the number of channels - currently, not more than forty to sixty different wavelength channels. This invention uses a wide-band light source, a two-dimensional, multi-channel, high-resolution wavelength dividing unit and a two-dimensional, multi-channel matrix of modulators. Because of this, the device described in the patent can easily provide more than 1,000 channels with different wavelengths simultaneously. Using the Information Compressor, the single fiber optic line can carry more than 1,000 Gigabits per second, thereby enormously increasing the capacity of communication lines.
Typical WDM systems use a separate single wavelength optical source to generate each channel. Each wavelength optical source requires wavelength stabilization circuitry in order to avoid cross-talk between adjacent channels. This impacts system cost and complexity as the number of channels is increased. LMGR's invention, however, can generate multiple modulated wavelength channels in WDM optical interconnect systems such as optical fiber. An optical light source generates a broadband optical signal having a plurality of wavelength signal components, and an optical coupling device collects the broadband optical signal, and directs this signal onto a wavelength separate device, which spatially separates the incident broadband optical signal into a two-dimensional array of discrete wavelength signal components.
In LMGR's compressor invention, each discrete wavelength signal is coupled from the wavelength separation device to a two-dimensional array of optical modulators, which generate an array of modulated discrete wavelength signal components, wherein each individual modulator within the modulator array receives and modulates a discrete wavelength signal component. An output device couples the two-dimensional array to an optical fiber.
This new compressor technology can also generate a wavelength division multiplexed signal wherein an input optical coupling device couples an incident broadband optical signal to a wavelength separation device comprising a linear array of wavelength selective mirrors. The invention additionally can receive and spatially separate WDM signals into an array of individually modulated channels. LMGR President Don Iwacha notes, "This new technology promises to have numerous applications in local-area networks. This invention complements, in a sense, LMGR's revolutionary switching mechanism, in which an electronically and computer controlled acousto-optical deflector set can randomly connect the channels from the array to the single fiber-optical line, resulting in extremely fast switching times over a wide-area network."
Adds LMGR CEO Barrington Simon, "This new compressor technology is the next in what management believes will be a series of telecommunication inventions that our research staff are developing and that management will bring to the market."
LMGR is a Nevada corporation specializing in the development of new applications of optical and light technologies. LMGR's breakthrough technology, which was originally developed in the former Soviet Union and brought to North America through the Company's Laser Show Systems (Canada) Ltd. subsidiary, employs sound waves to focus and direct lasers.
