A wavelength-sensitive variable fiber optic attenuator (VFOA) is introduced by incorporating the movable optical mirror with a fixed desired thin film filter (TF) in a compact in-line reflective architecture. Our TF-based wavelength-sensitive VFOA features low component count, high attenuation dynamic range, and high optical isolation. Experimental proof of concept using an off-the-shelf measured 1545.71-nm TF and a mechanically movable mirror shows a 4.64-dB optical loss, and a low polarization-dependent loss of 0.12 dB at the output port. A high optical attenuation dynamic range of >43 dB with a better than 30-dB optical isolation is obtained. Several proposed reflective wavelength-sensitive TF-based VFOAs can also be cascaded to form a low-cost, compact, multiwavelength amplitude controller.
