Mega-9 Optical supplies advanced narrow bandpass filter with high quality and fast delivery.
8. The optical filter of claim 1, further comprising: an optical directing device optically connected to the first and second optical elements; the optical directing device directing the light to the first reflective element, directing the first wavelength band reflected from the first reflective element to the second reflective element, and directing the second wavelength band reflected from the second reflective element to the output port of the optical directing device. 9. The optical filter of claim 8, wherein the optical directing device comprises at least one circulator. 10. The optical filter of claim 9 wherein the circulator receives the light at a first port of the circulator, directs the light to the first reflective element through a second port of the circulator, receives the first wavelength band at the second port, directs the first wavelength band to the second reflective element through a third port of the circulator, receives the second wavelength band at the third port, and directs the second wavelength band to a fourth port of the circulator. 11. The optical filter of claim 8 wherein said optical directing device comprises an optical coupler. 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.
