Commercial blue fiber laser based on 'telecoms' FBG filter

22 Jun 2007

JDSU has chosen Teraxion's "telecoms-grade" fiber Bragg grating (FBG) filters for its latest commercial 488 nm solid-state laser.

The "telecoms grade" narrowband FBG filter, developed and produced by TeraXion, is used as an ouput coupler for the 976 nm semiconductor pump laser deployed in JDSU’s fiber-based architecture. The output from the semiconductor laser is frequency converted to 488 nm by using a fiber-pigtailed periodically-poled lithium niobate waveguide, and the FBG is also used to accurately stabilize the frequency of the blue laser.

JDSU’s blue solid-state laser, which was released earlier this year, is targeting applications in biotechnology, semiconductor manufacture and general instrumentation.

"We are pleased that TeraXion's FBG filter is included in this design," said Len Marabella, Director of Marketing for Commercial Lasers at JDSU. "JDSU values their technical expertise and responsiveness to rapidly design and manufacture these highly customized FBG filters."

"We are thrilled to be involved in such an innovative and promising product," said Martin Guy, vice-president of product management and technology at TeraXion. "Being selected by JDSU is a recognition that the technology we have developed primarily for telecoms applications can now be integrated into other high-volume market opportunities".

TeraXion’s FBGs are widely used outside of the telecoms sector in diverse applications such as industrial lasers and fiber-optic sensors. From ultrafast to high-power functions, TeraXion offers reflectors, pulse stretchers/compressors and cavity dispersion compensators to meet the requirements of high-performance fiber lasers.
