1. A method of tuning a multifrequency optical channel device, the device having first and second optical waveguide segments coupled to an athermal resonator by first and second frequency selective couplers actuated by a first and second electrode, respectively, said athermal resonator tuned for mode frequency overlap with a plurality of designated frequency channels, the method comprising:

  • detuning a first coupling frequency of the first coupler relative to a second coupling frequency of the second coupler to achieve a detuning condition in which the first waveguide is decoupled from the second waveguide at said first and second frequencies;

    adjusting the first and second coupling frequencies to a vicinity of a desired frequency channel while maintaining said detuning condition; and

    retuning the first coupling frequency relative to the second coupling frequency until the first and second frequencies substantially equal each other and the frequency of the desired channel.
