This slide type wavelength tunable filter module can tune arbitrary wavelengths by changing positions of oxide dielectric type filters of which the thickness is precisely distributed in parallel to the substrate surface.

 

Features
– Realization of a wide wavelength tunable range (60 nm tunable)
– Low insertion loss
– Low variation in insertion loss
– Low variation in bandwidth
– Low PDL (polarization dependence loss) 
– Optional tandem implementation of optical filters (realization of the characteristics equivalent of 2-cavity)
– Manufacturing capability for customization of optical filters
