OZ Optics’ FF series of fixed filters transmit or block specific wavelengths of light as they travel through the optical fiber. Light from the input fiber is first collimated and passed through the filter. The beam is then focused into the output fiber.

Filter linewidths are normally defined in terms of full width at half maximum (FWHM). The standard filters used have a smooth, rounded transmission spectrum that is the result of a single Fabry Perot type cavity, simply made up of two reflectors separated by a fixed spacer of some thickness.

Other filter designs are available. For instance, flat top bandpass filters are made by stacking multiple cavities together. By increasing the number of cavities one can increase the roll-off slope therefore improving the out-of-band rejection level. Please contact AMS Technologies for custom filter designs that meet your requirements.

Fixed filters using single mode (SM), multi mode (MM) or polarization maintaining (PM) fibers are offered. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patch cords. However, OZ Optics can construct devices using other PM fiber structures. OZ Optics also carries some alternative fiber types in stock, please contact AMS Technologies for availability. If necessary, OZ Optics is willing to use customer supplied fibers to build devices.

For tunable filters refer to OZ Optics’ TF-100 series of digital tunable filters, TF-100-11 series of motor driven tunable filters, TF-11 series of manually adjustable polarization insensitive tunable filters, BTF-11 series of manually adjustable variable bandwidth tunable filters or BTF-100 series of motorized adjustable variable bandwidth tunable filters.
