FEBRUARY 20, 2007 -- Ibsen Photonics (search for Ibsen Photonics) has released a new, extended-wavelength version of its PING (Polarization Independent telecom gratings) gratings.
E-PING gratings will be produced on an OEM basis to specific customer requirements. However, with standard specifications E-PING gratings offer >90% diffraction efficiency, <0.25-dB PDL, and <0.25-dB WDL -- just as the current PING gratings do, according to the company. These specifications are upheld over an extended wavelength range of 1510-1596 nm.
Product Manager Kristian Buchwald explains, "Our PING gratings have been rapidly embraced by WSS/ROADM manufacturers, due to both performance and the inherent stability of our fused silica transmission grating technology.
"This development exemplifies the strength of this technology in offering stable performance over a broad bandwidth in addition to for example a great tolerance to incidence angle," he adds.
Torben Jacobsen, president and CEO of Ibsen, comments, "In addition to the exciting product development in itself, our high-resolution spectrometer business is boosted by this unique grating -- the E-PING grating has immediately been put to use within Ibsen by being incorporated into our extended-wavelength I-MON FBG Sensor System Interrogation Monitors."
