The VCSEL Technologies Division of AXT, Inc. (Nasdaq: AXTI) announced volume production of oxide confined VCSEL (vertical-cavity surface-emitting laser) arrays in 1x12 and 1x4 configurations. These arrays are used in such applications as short-reach optical interconnections and optical transceiver applications, and can include InfiniBand designs.
Each device within the 850 nm wavelength array can be modulated at data rates in excess of 2.5 Gbps, permitting optical designs with very high data rate products through the use of parallel data channels. The 1x4 array allows for modulation speeds reaching 10 Gbps data rates (OC-192) and the 1x12 array supports 30 Gbps rates. Typical power output for each VCSEL is 1.0mW with output slope efficiencies of 0.45-0.50 mW/mA. Both array forms are available immediately in production volumes, and can be tailored to meet a variety of customer specific product designs.
As data rates continue to increase, fiber optic connections become a solution for an increasing number of data communication products. For many future designs, fiber-optic connections will replace copper connections in such devices as computer servers. Designs may use parallel, multi-fiber connections to reach these higher data rates for uses in such short-reach interconnections as backplane, bus, and other subsystem connections.
