Abstract: A supercontinuum light source can include a seed laser arranged to provide seed pulses with a pulse frequency Fseed; a pulse frequency multiplier (PFM) arranged to multiply the seed pulses by converting pulses having the pulse frequency Fseed to pump pulses with a pulse frequency Fpump, where Fpump is larger than Fseed; and a non-linear element arranged to receive said pump pulses and convert said pump pulses to pulses of supercontinuum light. The PFM can further include a splitter for splitting pulses into first and second sub beams each having the same pulse frequency, where the PFM is configured such that the sub beams experience different delays; and a combiner for combining said first and second sub beams into a beam having the pulse frequency that is greater than said same pulse frequency. The splitter can have an uneven splitter ratio.

Abstract: A photonics frequency comb generator includes two integrated dies: an indium phosphide die laser of a first wavelength is grown on from, and a silicon photonics die having a microring resonator connected to the laser and frequency modulators. The microring resonator converts the first wavelength into a number of second wavelengths. One type of the microring resonator is a hybrid non-linear optical wavelength generator, comprising non-silicon materials, such as SiC or SiGe built on silicon to yield a non-linear wavelength generation. The second wavelengths are generated by adjusting the ring's geometric size and a distance between the ring and the traverse waveguide. Another type of microring resonator splits the first wavelength into a plurality of second wavelengths and transmits the multiple second wavelengths to filters and modulators, and each selects and modulates one of the second wavelengths in a one-to-one relationship. This frequency comb generator has applications in WDM/CWDM and multi-chip modules in high speed transceivers.

Abstract: A wavelength separating element is provided for separating a converted beam from a fundamental beam in an NLFC device, wherein the converted beam has a wavelength different from a wavelength of the fundamental beam. The wavelength separating element includes a first mirror surface and a second mirror surface opposite to the first mirror surface. The first and second mirror surfaces may have a high reflectivity of the converted beam relative to a reflectivity of the fundamental beam, and the first and second mirror surfaces are configured such that the fundamental and converted beams undergo multiple reflections between the first mirror surface and the second mirror surface to separate the converted beam from the fundamental beam. The fundamental and converted beams undergo at least three reflections at the first and second mirror surfaces, and/or undergo at least two reflections at one of the first mirror surface or the second mirror surface.
