EMCORE Introduces 850nm 1x4 and 1x12 Oxide VCSEL Arrays and High Speed Array Photodetectors for Very Short Reach Applications

New Arrays Target High-Speed Communication Markets Including OC-192, OC-768 and Infiniband(SM)

Somerset, NJ. EMCORE Corporation (NASDAQ:EMKR) today announced the availability of its first 850 nm 1x4 and 1x12 Oxide Vertical Cavity Surface Emitting Laser (VCSEL) arrays and its high speed gallium arsenide (GaAs) photodetector arrays, capable of data rates up to 3.125 Gbps.

EMCORE s Optical Device Division in Albuquerque, NM has designed the new VCSEL arrays and photodetector arrays specifically to serve the emerging requirements for short-reach optical interconnects in telecommunications modules and computing systems. It is anticipated that these components will serve as the optical links in a new family of array transceivers.

As Internet traffic continues to grow more bandwidth is needed to carry the data. VCSEL arrays and photodetector arrays are ideal for providing high speed optical interconnects between switches routing Internet and electronic data. VCSEL arrays and photodetector arrays are also ideal for providing high-speed cost-effective links to enable faster data transmission without increasing the size of the switch. Optical arrays are instrumental in developing optical backplanes for high-speed computers and are part of the emerging Infinband(SM) standard. The total available market for array transceivers is expected to be more than $1 billion by 2003, according to ElectroniCast Corporation.

"The exponential growth of the Internet continues to drive the demand for short-reach parallel optical interconnects, as it pushes the limits of available bandwidth and network capacity," said Reuben Richards, President and CEO of EMCORE. "EMCORE s new array technology shows our commitment to meeting customer requirements for extremely high data transmission. This latest product release further solidifies EMCORE s position as the leading provider of optical components for the Internet infrastructure."

EMCORE s oxide VCSEL arrays and photodetector arrays provide the critical components of array transceivers. EMCORE is the first company in the industry to offer transceiver manufacturers an array and photodetector combination capable of both transmitting and receiving data. The oxide VCSEL arrays and photodetector arrays are developed using semiconductor manufacturing processes. EMCORE has developed leading edge technology and processes that provide the small form factor and tight distributions required for developing cost effective high speed optical interconnects.

The VCSEL arrays provide a cost effective solution and enable efficient system designs at typical thresholds of 1.5mA and slope efficiencies of 0.4mW/mA. EMCORE s oxide VCSEL arrays, available with 250-micron pitch, provide low current thresholds and high uniformity across the array for threshold, output power and slope efficiency. The 1x4 array is capable of up to 10 Gbps transmission speeds, while the 1x12 has a transmission speed of 30Gbps. EMCORE s photodetector arrays operate up to speeds of 3.125Gbps and provide the efficiency required for high speed data transmission. These new VCSEL arrays and photodetector arrays are an expansion of EMCORE s successful family of 850nm VCSELs.
