12. The optical filter of claim 1, wherein the first reflection wavelength and the second reflection wavelength are substantially aligned to reflect a portion of the aligned wavelength bands to an output port. 13. The optical filter of claim 1, wherein one of the first and second reflective filter functions comprises one of a Gaussian, rectangular and ramp shape. 14. The optical filter of claim 1, wherein one of the first and second reflective elements is fully apodized and the other of the first and second reflective elements is partially apodized. 15. The optical filter of claim 1, wherein the first reflection wavelength is offset a predetermined spacing from the second reflection wavelength. 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.
