Noise Suppression in a 10 GHz Octave-Spanning Frequency Comb

https://doi.org/10.1109/IPC53466.2022.9975623

Sekhar, Pooja; Fredrick, Connor; Wu, Tsung-Han; Swartz, Stephanie; Diddams, Scott A. (November 2022, 2022 IEEE Photonics Conference (IPC))

We demonstrate a 10 GHz octave-spanning frequency comb from a 1550 nm resonant waveguide-type electro-optic comb generator. The impact of cavity filtering on the amplified spontaneous emission and shot noise is studied experimentally and theoretically.

10 GHz Frequency Comb Generation in Lithium Niobate Waveguides with Chirped Poling

https://doi.org/10.1364/FIO.2023.FTh3E.5

Sekhar, Pooja; Wu, Tsung-Han; Ledezma, Luis; Fredrick, Connor; Sekine, Ryoto; Guo, Qiushi; Briggs, Ryan; Marandi, Alireza; Diddams, Scott A (January 2023, Optica Publishing Group)

We demonstrate efficient 10 GHz frequency comb generation using chirped periodically poled nanophotonic lithium niobate waveguides. Spectral coverage across the UV and visible is achieved with pulse energies less than 50 pJ.

Ultraviolet to Near-infrared Frequency Comb Generation in Lithium Niobate Nanophotonic Waveguides with Chirped Poling

https://doi.org/10.1364/CLEO_QELS.2022.FW4J.2

Wu, Tsung-Han; Ledezma, Luis; Fredrick, Connor; Sekhar, Pooja; Sekine, Ryoto; Guo, Qiushi; Briggs, Ryan; Marandi, Alireza; Diddams, Scott A. (January 2022, Conference on Lasers and Electro-Optics)

We demonstrate thin-film lithium niobate waveguides with chirped poling periods for efficient supercontinuum viaχ⁽²⁾andχ⁽³⁾nonlinearities. With picojoule energies, we generate gap free frequency combs spanning 330 to 2400 nm.
