21. The optical filter of claim 1 further includes a heating element for varying the temperature of the first optical element to tune the first reflective element to reflect the selected first wavelength band. 22. The optical filter of claim 1, wherein the at least one of the first and second optical waveguides has outer dimensions along perpendicular axial and transverse directions, a first portion of the at least one of the first and second optical waveguides having an outer dimension being at least 0.3 mm along said transverse direction, at least a portion of the first portion having a transverse cross-section which is continuous and comprises a substantially homogeneous material; and the at least one of the first and second optical waveguides being axially strain compressed so as to change the at least one of the first and second reflection wavelengths. 23. The optical filter of claim 22, wherein both of the first and second optical waveguides is tunable to change each of the respective first and second reflection wavelengths. 5. The optical filter of claim 4, wherein the displacement sensor includes a capacitance sensor coupled to the first optical element for measuring the change in the capacitance that depends on the change in the displacement of the first optical element. 6. The optical filter of claim 1, wherein both of the first and second optical elements is tunable to change each of the respective first and second wavelengths. 7. The optical filter of claim 6 further comprising: a first compressing device for compressing axially the first element to tune the first reflective element, wherein the first reflective element is written in the longitudinal direction in the first optical element; and a second compressing device for compressing axially the second optical element to tune the second reflective element, wherein the second reflective element is written in the direction in the second optical element.
