Generation of frequency combs and sinc-shaped nyquist pulse trains with a large bandwidth and tunable repetition rate

摘要

A method for generating an optical frequency comb with a defined number of frequency comb lines with an adjustable spacing therebetween includes generating an input frequency comb comprising a multiplicity of input frequency comb lines with a light source. Individual frequency comb lines having an identical frequency spacing are filtered out of the multiplicity of input frequency comb lines so as to obtain filtered frequency comb lines. A first modulating of the filtered frequency comb lines is performed at a first modulation frequency so as to generate first sideband lines. The first sideband lines are generated by the first modulating so that the filtered frequency comb lines and the first sideband lines have an identical frequency spacing.

1. A method for generating an optical frequency comb with a defined number of frequency comb lines with an adjustable spacing therebetween, the method comprising:
generating an input frequency comb comprising a multiplicity of input frequency comb lines with a light source; filtering out of the multiplicity of input frequency comb lines the individual frequency comb lines having an identical frequency spacing so as to obtain filtered frequency comb lines; and preforming a first modulating of the filtered frequency comb lines at a first modulation frequency so as to generate first sideband lines, wherein the first sideband lines are generated by the first modulating so that the filtered frequency comb lines and the first sideband lines have an identical frequency spacing.
