Claim 17:
18. A method for generating and using an optical frequency comb, the method comprising:
generating an optical frequency comb;
applying a filter in a first configuration to the generated optical frequency comb, wherein the filter has a first pass-band having a first frequency and a second pass-band having a second frequency, to select a first frequency line of the optical frequency comb corresponding to the first frequency of the first pass-band, and wherein, in the first configuration, a second frequency line of the optical frequency comb does not correspond to the first frequency of the first pass-band or the second frequency of the second pass-band;
altering the filter to a second configuration, raising a frequency of the first pass-band to a third frequency and raising a frequency of the second pass-band to a fourth frequency; and
applying the altered filter in the second configuration to the generated optical frequency comb to select the second frequency line of the optical frequency comb corresponding to the fourth frequency of the second pass-band, wherein, in the second configuration, the first frequency line of the optical frequency comb does not correspond to the third frequency of the first pass-band or the fourth frequency of the second pass-band.
