Claim 34:
35. An optical filter comprising:
a first bandpass filter having a first center wavelength within a first wavelength band, the first bandpass filter including a plurality of first Bragg reflective layers and at least one first cavity provided between the plurality of first Bragg reflective layers;
a first multi-layer provided on the first bandpass filter, the first multi-layer having a plurality of first material layers configured to block light of wavelength bands different from the first wavelength band;
a second bandpass filter having a second center wavelength within a second wavelength band, the second bandpass filter including a plurality of second Bragg reflective layers and at least one second cavity provided between the plurality of second Bragg reflective layers; and
a second multi-layer provided on the second bandpass filter, the second multi-layer having a plurality of second material layers configured to block light of wavelength bands different from the second wavelength band,
wherein the first bandpass filter and the first multi-layer are provided on a same plane as the second bandpass filter and the second multi-layer, and
wherein the first multi-layer comprises a plurality of material layers provided above an upper most Bragg reflective layer among the plurality of first Bragg reflective layers.
