1. A colinear light source comprising:

  • a first active optical waveguide formed in a first semiconductor material configured to emit a first light spectrum; and

    a second active optical waveguide formed in a second semiconductor material configured to emit a second light spectrum, wherein the second active optical waveguide is configured to receive the first light spectrum from the first active optical waveguide at an entrance facet of the second active optical waveguide, and wherein an exit facet of the second active optical waveguide emits colinear light that includes the first light spectrum and the second light spectrum, the first semiconductor material being different from the second semiconductor material.
