Claim 2:
3. The method of claim 1, wherein the optical frequency comb is a first optical frequency comb, and the filter is a first filter, the method further comprising:
generating a second optical frequency comb;
applying a second filter in a first configuration to the second generated optical frequency comb to select a first frequency line of the second optical frequency comb, wherein, in the first configuration, the first frequency line of the second optical frequency comb aligns with a first pass-band of the second filter, and wherein, in the first configuration of the second filter, a second frequency line of the second optical frequency comb does not align with a second pass-band of the second filter;
altering the second filter to a second configuration of the second filter to shift the first pass-band of the second filter and the second pass-band of the second filter to a shifted first pass-band of the second filter and a shifted second pass-band of the second filter; and
applying the altered second filter in the second configuration to the generated second optical frequency comb to select the second frequency line of the second optical frequency comb, wherein, in the second configuration, the second frequency line of the second optical frequency comb aligns with the shifted second pass-band of the second filter, and wherein, in the second configuration of the second filter, the first frequency line of the second optical frequency comb does not align with the shifted first pass-band of the second filter.
