OZ Optics’ WDM series of polarization maintaining wavelength division multiplexers (WDMs) are used to combine light of different wavelengths into a single fiber. The light from each fiber is first collimated. The collimated beams are then combined using a dichroic filter, with typically the longer wavelength transmitted from port T, the shorter wavelength reflected from port R. The combined beams are then focused into the output fiber at Port 1. The device typically maintains polarization to better than 20 dB for 1300 and 1550 nm applications. OZ Optics manufacturers wave division multiplexers for both telecom and non-telecom applications. One advantage of OZ Optics’ WDMs is that different fiber types can be used on the input and output ends of the device. This is especially useful in fiber amplifier applications, when the Erbium doped fibers have a different core diameter and numerical aperture. WDMs with 1 dB typical insertion loss have been made this way.

OZ Optics also offers source to fiber wavelength division multiplexers, where the sources are mounted directly onto the device. Miniature size WDMs are ideal for telecommunication applications such as drop/add filters for either coarse WDM (CWDM) or dense WDM (DWDM) applications. They are also used for combining 980 to 1080 nm pump light with 1550 nm signals in erbium doped fiber amplifiers (EDFAs).

Variants with higher extinction ratios are available on request. OZ Optics specializes in manufacturing custom designed WDM's. Contact AMS Technologies for further information.
