Claim 0:
1. 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 to select a first frequency line of the optical frequency comb, wherein, in the first configuration, the first frequency line aligns with a first pass-band of the filter, and wherein, in the first configuration, a second frequency line of the optical frequency comb does not align with a second pass-band of the filter;
altering the filter to a second configuration to shift the first pass-band and the second pass-band to a shifted first pass-band and a shifted second pass-band; 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, wherein, in the second configuration, the second frequency line aligns with the shifted second pass-band of the filter, and wherein, in the second configuration, the first frequency line of the optical frequency comb does not align with the shifted first pass-band of the filter.
