manufacturing process for controlling quality and performance.
The Oclaro VCSEL team has been leading the commercialization of VCSELs for demanding industrial and consumer applications and has accumulated industry-leading expertise in all aspects of VCSEL design and manufacturing.
“The ability to scale to high volume reliably and cost-effectively is a strength that Oclaro perfected in the telecom space and is now leveraging in emerging high volume markets,” said Yves Le Maitre, Executive VP and Division Manager at Oclaro. “Oclaro’s unique expertise and manufacturing capability is driving the adoption of lasers into adjacent and diverse photonics markets. As a result, Oclaro diode lasers are now being incorporated into a wide range of products being used by home consumers across the globe.”
Oclaro VCSELs are currently powering high- volume consumer electronics devices such as computer mice and finger navigation engines for mobile devices. In addition, VCSEL-based optical cables are emerging as a replacement for the existing electrical cable technology in mainstream computing devices because electrical solutions are approaching their practical limits for speed and length.
VCSEL-based optical interconnects, on the other hand, do not have these same limitations because they transmit data using light instead of electricity. The achieved 100M milestone exemplifies Oclaro’s leading position as a laser diode supplier into these emerging volume markets.
Oclaro’s 808nm High Performance LDs are Very Efficient
Oclaro, a provider of optical communications and laser solutions has a new line of laser diodes that the company says feature the highest level of efficiency and performance in the industry.
Combining laser diode technology from Oclaro’s Zurich facility with the packaging technology from Oclaro’s Tucson site, this new line of laser diodes,

is being showcased at Photonics West in California next week.
These are Oclaro’s first laser diodes to ship in volume for products originally developed in Tucson, including the collimated bar series and Prosario Series. Primarily used for diode pumped solid state lasers and direct medical applications, these new integrated platforms provide end-users and integrators another level of performance with a more compact size, more efficient thermal management and increased power.
“We are proud to see our integration efforts delivering the excellent results we anticipated,” said Yves Le Maitre, Executive VP and Division Manager at Oclaro. “These new laser diodes demonstrate how we can take advantage of Oclaro’s economies of scale and expertise to deliver the highest level of cost savings, operations efficiencies and manufacturing excellence − and then leverage the resulting technology across multiple Oclaro product lines.”
Targeted at solid state laser pumping, direct diode applications and medical markets, Oclaro’s new line of 60W 27%FF (Fill Factor) bars and 80W 50%FF bars are developed for CW (Continuous Wave) operation on a conductive heat-sink. The 60W and 80W diode bars offer leading brightness and power on an industry standard CS type assembly, which is fully compatible to previously released products. The increased brightness of the 60W product makes it most suitable for beam shaping and fiber coupling applications, while the 80W product excels in pumping applications and line sources.
These laser diode bars represent the first Oclaro E2 facet passivated and hard-soldered bars to be incorporated in the company’s collimated bar series and fiber coupled Prosario series. By integrating this technology into these two series, Oclaro can improve their output power, efficiency and reliability in order to offer customers a higher performing solution. This is another example of how Oclaro is taking its core technology and leveraging it across multiple product lines and markets.
The new high-powered laser products feature the Oclaro E2 mirror passivation process which protects the front facet of the bar against catastrophic optical mirror damage. In addition, the telecom grade AuSn (gold tin) hard solder makes the product
