Optical wavelength switch using strain-controlled fiber Bragg gratings

Fiber Bragg gratings have been studied intensively these years, because of their high potentiality in being applied in wavelength division multiplexing fiber transmission systems. As one of their useful characteristics, Bragg reflection wavelength can be changed by applying stress to the grating region. We obtained a maximum wavelength shift of 6.08 nm at 300 electric pulses to an electrically-driven micro-step stage. We investigated its possibility of optical wavelength switching. We achieved maximum extinction ratios of 26.0 dB and 25.9 dB for reflected and transmitted lights, respectively, and realized a switching time of 8 - 10 msec.
