Abstract
Embodiments herein describe combining multiple optical signals so these signals propagate in the same direction in the same optical mode and polarization. In one embodiment, the techniques discussed herein are used to combine a reference laser with a frequency comb so that supercontinuum generation can then be performed to increase the frequency range of the frequency comb so that it includes the frequency of the reference laser.
Claims20
A system, comprising:
- a photonic integrated circuit (PIC) comprising a supercontinuum generator;
- and
- a combiner configured to combine a reference laser and a frequency comb, wherein an output of the combiner is coupled to an input of the supercontinuum generator.
A method, comprising:
- combining a reference laser and a frequency comb to generate a combined optical signal;
- and
- performing supercontinuum generation on the combined optical signal.
