16. The optical filter of claim 1, wherein at least one of the first and second optical elements have an outer cladding and an inner core disposed therein, wherein the at least one of the first and second reflective element comprises a grating disposed in a longitudinal direction of the inner core. 17. The optical filter of claim 16, wherein the at least one of the first and second optical elements comprises: an optical fiber, having a reflective element written therein; and a tube, having the optical fiber and the reflective element encased therein along a longitudinal axis of the tube, the tube being fused to at least a portion of the fiber. 18. The optical filter of claim 16, wherein the at least one of the first and second optical elements is an optical waveguide having an outer transverse dimension of at least 0.3 mm. 19. The optical filter of claim 16, wherein the at least one of the first and second optical elements is an optical fiber. 20. The optical filter of claim 1 further includes a straining device for tensioning axially the first optical element to tune the first reflective element, wherein the first reflective element is disposed along an axial direction of the first optical element. 24. The optical filter of claim 22, 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. 25.
