Honeywell moves into full production of 2.5 Gb/s oxide VCSELs
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 PECL (Positive Emitter Coupled Logic) or ECL (Emitter Coupled Logic) gates possible and eases driver design.
Paul Chapman, Vice President and General Manager of the VCSEL Products Division, has high expectations for the Oxide line. "We are very excited about the release of our new oxide isolated VCSEL product family. The cornerstone of our success in the VCSEL product area has been our attention to detail with respect to the reliability of our VCSEL products.
Extensive work in understanding the oxide VCSEL process interactions and effects on long-term reliability has resulted in a product approaching the reliability of our successful ion implant VCSELs. These new oxide VCSEL products represent the next step in providing the improved high speed operating characteristics necessary for many new data com/telecom applications."
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.
Various packaging options include fiber receptacle sleeve (SC & LC compatible), and packages that mate the VCSEL with a high speed detector in a fixed or pluggable style (MTRJ & LC compatible) Optical Front End as well as various array configurations. While the Oxide VCSEL line has just been formally released for general sale, the release represents the culmination of extensive design work at Honeywell, which is supported with extensive reliability data and months of actual application by a limited customer list.
For a limited time, qualified customers can request a Honeywell Oxide VCSEL design kit and register for the upcoming Internet training seminar, "Oxides, the Future is Now!" at www.honeywell.com/sensing/vcsel
Honeywell is a leader in VCSEL technology and offers a broad range of VCSEL and detector products in several versatile packages. Honeywell was the first to offer a commercially available VCSEL in 1996, and continues its leadership with the broadest line of reliable VCSEL components available today.
