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. The optical filter of claim 22, wherein one of the first and second filter functions comprises one of a Gaussian, rectangular and ramp shape. 26. The optical filter of claim 22, 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. 27. The optical filter of claim 22, wherein the first reflection wavelength is offset a predetermined spacing from the second reflection wavelength. 28. The optical filter of claim 22, wherein at least one of the first and second reflective elements includes a Bragg grating. 1. An optical filter comprising: a first optical element including a first reflective element for receiving light and reflecting a first wavelength band of the light centered at a first reflective wavelength, the first reflective element characterized by a first reflective filter function; and a second optical element, optically connected to the first a second optical element to receive the reflected first wavelength band of the light, including a second reflective element for reflecting a second wavelength band of the light centered at a second reflection wavelength, the second reflective element characterized by a second reflective filter function, whereby at least one of the first reflective filter function and the second reflective filter function is not substantially flat over a substantial portion of the respective first or second reflective filter function, and the first wavelength band and the second wavelength band overlap spectrally.
