Honeywell announces full production release of 2.5Gb/s oxide VCSELs
Honeywell announces full production release of 2.5Gb/s oxide VCSELsKeywords: Laser sensors, Light, Honeywell
The VCSEL Products Division of Honeywell has announced the production release of its oxide-isolated VCSEL product line, a set of high-performance 850nm vertical cavity surface-emitting lasers (VCSELs) packaged for high-speed ( > 2GHz) data communications (see Plate 4).
The high radiance VCSELs are designed to convert electrical current into optical power that can be used in fiber optic communications and other applications. As the current varies above threshold, the light intensity increases proportionally. The oxide product combines all the performance advantages of the VCSEL with a custom designed power monitor diode. The power monitor diode can be used with appropriate feedback control circuitry to set a maximum power level for each VCSEL. In addition, built-in power attenuation reduces the effective slope efficiency. These combined features simplify design for high data rate communication and eye safety. In addition, the low drive current requirement makes direct drive from positive emitter coupled logic (PECL) or emitter coupled logic (ECL) gates possible and eases driver design.

The Honeywell oxide VCSELs are designed to be used with inexpensive silicon or gallium arsenide detectors, but excellent performance can also be achieved with some indium gallium arsenide detectors. Honeywell offers VCSEL complementary matching high speed detectors.
