Finisar has developed a line of high power, high efficiency VCSEL arrays. They are fabricated at 860nm as traditional P side up top emitting devices, leveraging Finisar’s existing VCSEL fab and test processes for low cost, high volume capability. A

The next individual-channel VCSEL (Vertical Cavity Surface Emitting Laser) node for data communications is 25 Gbps or higher. Providing the required reliability becomes ever more challenging as the speeds increase, but possible with proper design.

For nearly twenty years most models of VCSEL wearout reliability have incorporated Arrhenius activation energy near 0.7 eV, usually with a modest current exponent in addition. As VCSEL production extends into more wavelength, power, and speed regimes

Commercial demand for optical transceivers operating at 14Gbps is now a reality. It is further expected that communications standards utilizing 850nm VCSELs at speeds up to 28Gbps will be ratified in the near future. We report on the development and

It has been traditional in discussions of VCSEL reliability to consider it as having a single major wearout component, with known temperature and current acceleration. Beyond this major component all other causes of failure are lumped into a small ra

In this paper we describe progress in moving VCSELs toward production-ready status in several applications, among others including substantially higher modulation speeds (14-25 Gbps, or even higher) than in current production. In addition we describe

In 2007 Finisar® completed the transfer of an entire epitaxial and fabrication line from one facility to another. During this period, reliability models had to be re-validated and product continuity maintained. In this paper we describe the activiti

After some thirty years of materials analyses into the failure behavior of III-V semiconductor lasers, manufacturers of these devices still regularly encounter new failure mechanisms. This is due mainly to the implementation of progressively more com

During a year of substantial consolidation in the VCSEL industry, Honeywell sold their VCSEL Optical Products Division, which has now officially changed its name to Advanced Optical Components (AOC). Both manufacture and applied research continue, ho

Honeywell continues to be the world’s leading supplier of VCSELs operating at 850 nm. This paper will cover new commercial application areas for 850-nm VCSELs, and will present new findings in VCSEL reliability science. In particular, newly-develop
