1. A compression-tuned optical device comprising:

  • an optical waveguide including an inner core disposed within an outer cladding and a grating disposed within the inner core, the grating reflecting a first reflection wavelength of light back along the inner core and propagating remaining wavelengths of light through the grating, the optical waveguide including a pair of opposing surfaces; and

    a compressing device engaging the opposing surfaces of the optical waveguide for compressing the opposing surfaces towards each other to tune the grating to change the reflection wavelength of light reflected back along the inner core.
