Narrowband Tuneable Filter

Narrowband Tuneable Filter is available through BBN International for customers seeking specialist optical, electronic and industrial technology solutions.

Narrowband Tuneable Filters of WLTF-NM- & WLTF-NE- series are built based on free-space optical Fourier transformation combing with diffraction grating. Patent-pending optics design offers great options of bandwidth with unprecedented low insertion loss and polarisation dependent loss (PDL). Precise tuning mechanism enables filters to provide high wavelength resolution and repeatability. Both of manual and electric version filters are available over X-, O-, S-, C-, & L- bands. Wavelength-tuning is actuated by either a precise micrometer driver or a built-in micro motor connected to a PC through a USB (I²C or SPI) interface in which actuation is monitored by a built-in encoder and controlled dynamically in a closed-loop. Motor control software is provided.

Key features: Operating range available over X-, O-, S-, C- and L-bands; Up to 200nm wavelength tuning range; Unprecedented low insertion loss and PDL; High optical power handling; Accurate and uniform bandwidth over whole tuning range; Down to 0.1nm FWHM bandwidth; High out-band suppression; Customised versions available on request.

Typical applications: ASE noise suppression; DWDM channel filtering; WDM wavelength tuning; Pulse shaping; FBG sensor interrogation; Tuneable fibre lasers.
