Picolight cross licenses laser technology - Business - Picolight entered a cross-license agreement with the Honeywell - Brief Article

Fiber Optics Weekly Update, Feb 6, 2004

Picolight, a supplier of oxide VCSEL based transceivers and VCSEL subassemblies, announced that it entered into a cross-license agreement with the Honeywell VCSEL Optical Products business for laser-related intellectual property. The agreement--signed November 2003--applies to four Picolight patents and one Honeywell patent, which pertain to "oxide confined" VCSEL designs.

On Jan. 26, Honeywell and Finisar Corp. announced a definitive agreement under which Finisar has agreed to acquire the VCSEL Optical Products business. The cross-license agreement will transfer to Finisar when the transaction closes during the first calendar quarter of 2004.

Oxide VCSEL sources dominate short-reach Ethernet and Fibre Channel optical interconnects due to their speed, signal integrity, reliability and manufacturability. The use of oxide confinement in the design enabled VCSEL based transceivers to reach 2 Gbps, 4 Gbps and 10 Gbps data rates. The technology included in the license agreement pertains to key aspects of oxide VSCELs found in existing and future Picolight products. Specific terms of the agreement were not disclosed.
