Abstract:
1. A method, comprising the steps of: providing a plurality of optical sources on a substrate, such that a first one of the plurality of optical sources is configured to generate a first optical signal having a first wavelength, and a second one of the plurality of optical sources is configured to generate a second optical signal having a second wavelength different than the first wavelength, the first one of the plurality of optical sources supplying the first optical signal with a first power and the second one of the plurality of optical sources supplying the second optical signal with a second power level greater than the first power level; and providing an optical combiner on the substrate, the optical combiner having first and second inputs configured to receive the first and second optical signals, respectively, the optical combiner having an associated passband envelope that has a transmission that varies substantially quadratically as a function of wavelength, wherein the optical combiner has a first loss at the first wavelength and a second loss at the second wavelength, the first loss being less than the second loss.
