The pass-band of the filter is dependent on the incident angle of light incident upon the filter. The first lens is positioned on a first side of the filter. The second lens is positioned on a second side of the filter. The first holder is configured to hold at least first, second, third, and fourth fibers proximate to the first lens. The first holder is also configured to hold a center of the second and the fourth fibers on opposite sides of a line connecting a center of the first and the third fibers. The second holder is configured to hold at least fifth and sixth fibers proximate to the second lens.
