Ultrafast low-power VCSEL chip

MAY 19, 2009 -- VI Systems GmbH Technologies has announced a low-power V20-850C vertical-cavity surface-emitting laser chip for short-range fiber-optic transceivers for data communications and interconnect applications.

MAY 19, 2009 -- VI Systems GmbH Technologies, a fabless developer and manufacturing company of ultrafast laser and photodetector components, has announced a low-power V20-850C vertical cavity surface emitting laser (VCSEL) chip for short-range fiber-optic transceivers for data communications and interconnect applications. VI Systems GmbH's new laser chip operates with up to 20 Gbps and is designed for multimode fiber systems that operate at a nominal wavelength of 850 nm.

The new VCSEL operates at moderate current densities of <3 kA/cm2. Compared to traditional VSCSEL designs the V20-850C can be operated at much higher modulation speed but with same current density, VI Systems says. The company further asserts that there is essentially no temperature dependence in the VCSEL's performance up to a temperature of 100 degree C.

Engineering samples are available now. Mass production is scheduled for Q3 2009.
