CyOptics Introduces 10Gbps Electro-Absorption Modulator; Based on Indium Phosphide, it Offers an Alternative to Lithium Niobate Modulators for Optical Transmission.Business Editors & High Tech Writers WALTHAM, Mass.--(BUSINESS WIRE)--Sept. 11, 2001 CyOptics Inc., a leading developer of Indium Phosphide phosphide Any of a class of chemical compounds in which phosphorous is combined with a metal. Phosphides exhibit a wide variety of chemical and physical properties. Phosphides that are rich in metal have high melting points and are hard, brittle, and chemically inert; these based active optical components, today introduced its 10Gbps Electro-Absorption Modulator A semiconductor diode that modulates light from a laser that is separate from it, but may be fabricated on the same wafer. Turning the current on causes absorption of the light. See fiber optics glossary. (EAM (1) (Enterprise Asset Management) The management and control of the information technology assets within the enterprise. The asset management repository includes a description of the asset as well as contract information pertaining to its acquisition. ). The EAM is a highly compact, low cost modulator Modulator Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. , targeted at replacement of the traditional Lithium Niobate Lithium niobate (LiNbO3) is a compound of niobium, lithium, and oxygen. It is a colorless solid that is insoluble in water. Its melting point is 1257 °C and its density is 4.65 g/cm³. Its CAS number is []. modulators in metro and long reach applications. Transmission experiments show that the CyOptics EAM provides error free 10Gbps operation on uncompensated uncompensated (  n·kômˑ·p spans of over 100km. This performance translates to transmission of 500km and further in long reach WDM (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. applications, which include chromatic dispersion compensation. "The results of transmission experiments indicate that our 10Gbps EAM is well suited for use in long haul applications, while its small size and lower total cost of ownership make it ideally suited for metro applications as well," said Irving Wang, CyOptics Product Line Manager for the EAM. Fabricated using mature semiconductor processing technology, the Indium Phosphide (InP)-based EAM provides excellent manufacturability, a crucial advantage in an industry striving to lower cost while improving performance. The EAM is hermetically her·met·ic also her·met·i·cal adj. 1. Completely sealed, especially against the escape or entry of air. 2. Impervious to outside interference or influence: sealed in a compact, 0.75" X 0.63" package, providing substantial space savings over alternative solutions. In addition, the EAM's low drive voltage requirements allow the use of a wide selection of low-cost drivers, with prices of $130-400, in contrast to $1,000 and more for typical Lithium Niobate modulator drivers. Pricing for the 10Gbps EAM itself is $1,500 at quantities of 1,000 units. EAMs use the electro-absorption effect (Franz-Keldysh effect) in InP to modulate light. The actual device, which is under 1 mm in length, is coupled to a high-speed electronic drive signal, and to an optical fiber. When negative voltage is applied, the device becomes opaque and light is blocked. At zero voltage, the device is transparent and light passes through it. Acting as a shutter, the 10Gbps EAM can be turned on and off 10 billion times a second, sending 10 billion bits of data per second over an optical network. InP has been used since the early 1980s in numerous optoelectronic components, including lasers and receivers. Its use in high speed modulation paves the way to highly integrated, compact devices for optical transmission.
