Claim:
1. An optical receiver, comprising: an optical source configured to transmit a multiplexed optical signal including a first data signal comprising a first wavelength and a second data signal comprising a second, different wavelength; a first optical filter arranged to receive the multiplexed optical signal from the optical source, wherein a material of the first optical filter permits the first data signal to pass through the first optical filter and reflects the second data signal; a mirror arranged to receive the second data signal reflected from the first optical filter and redirect the second data signal; a second optical filter arranged to receive the second data signal after being reflected by the first optical filter, wherein a material of the second optical filter permits the second data signal to pass through the second optical filter; and a ball lens configured to receive the first and second data signals after passing through the first and second optical filters and focus the first and second data signals onto individual detectors.
