ABSTRACT:
An optical device comprising a planar waveguide, and a second portion spaced from the planar waveguide portion by a gap to receive optical signals therefrom, the planar waveguide portion including: means integrated therein for separating an input beam into sub-beams having different central wavelengths; the second portion having closely spaced waveguides for receiving the sub-beams of light and having passive temperature compensation means coupled therewith for enhancing the coupling of the optical signals having predetermined wavelengths provided by the first block with the closely spaced waveguides.
