New Broadband Fibre-to-Fibre Isolators for the Super-Luminescent Light Emitting Diode (SLED) Market

6 March 2009

Lambda Photometrics Ltd are pleased to announce a new line of fibre-to-fibre optical isolators from Optics for Research Inc. (OFR), specifically designed for use in Super-Luminescent Light Emitting Diode (SLED or SLD) applications. These isolators provide high isolation and low insertion loss over broad bandwidths and are available for common SLED wavelength ranges in the 750nm to 900nm region.


OFR_SLED

These isolators use OFR’s proven IO-F series optical engine, and two platforms are available for single or dual chip SLED requirements. For single chip SLED applications the IO-F-SL1 fibre isolator provides superior performance over a spectral bandwidth of 70nm. For dual chip SLED systems the IO-F-BB-SL2 provides coverage over a 100nm bandwidth.

Isolation at the centre wavelength typically exceeds 35dB, and is maintained to at least 20dB at the bandwidth FWHM points for both models. Optical power handling capability is 3Watts in the forward and reverse directions, and the compact packages are supplied with 1 metre SM800 fibre pigtails.

If you manufacture or are using SLD/SLED sources, and optical feedback is a problem, then you need an optical isolator from Lambda/OFR. For further information please click here to contact us by email, alternatively call us on 01582 764334.
