We report on strong effects of uniaxial stress applied on in-fiber grating. Under the stress the reflection peak splits into two due to the elasto-optically induced birefringence. The separation between the two peaks increases with the stress, they broaden and shift. By modulating the pressure using a PZT disc at frequencies up to 1 MHz, we obtained modulation of the reflectivity which varies with the wavelength within the grating reflection band.
