  • Abstract
    We present microbend long-period fiber gratings that can be used as electrically loss-tunable band-rejection filters. The tunability of wavelength-selective loss is based on variable perturbation of the fiber induced by an electromagnet in combination with a steel coil spring. A dynamic loss amplitude of 11 dB is obtained and the response time measured is 16-18 ms.
