The Optical Frequency Comb Is A Spectrum Of Evenly Spaced Narrow Laser Lines. Optical Frequency Combs Have Revolutionized Time And Frequency Metrology By Linking Microwave And Optical Frequencies. However, Realizing Their Full Potential In A Broader Range Of Applications Such As 3D Imaging, Environmental Sensing, Lidar, And High-Speed Optical Communications, Is Conditioned By The Availability Of Inexpensive Highly Miniaturized Devices.
Progress In Integrated Optics Towards Chip-Scale Frequency Combs Has Made Significant Strides In Recent Years. Ugent Has Been At The Forefront Of This Evolution. It Has Developed Unique Technologies In Heterogeneous Integration, Enabling The Long-Missing Functionality Of Optical Gain On A Chip. This Unlocks The Full Integration Of Combs, In Particular, In The Infrared, But Also In The Near-Infrared Range (800-1100 Nm), The Key To Sensing In Water-Dominated Media As Encountered In Biological Samples, E.G. In Optical Coherence Tomography Setting, Food Industry, And Environmental Sensing.
In Molokai Ugent Will Engage In A Close Collaboration With The Group At Mbi Which Is The Pioneer Of The Applications Of Frequency Combs Applied To Dual-Comb Interferometry And, In Particular, The Initiator Of The Extension Of Frequency-Comb Techniques To 3D Imaging, And To Raman Spectroscopy. In This Way In Molokai, We Aim To Leverage The Latest Breakthroughs In Chip-Scale Frequency-Comb Technology To Transition These Technologies In A Real-Life Setting.
Molokai Will Work Further On Our Initial Dual-Comb Results To Make A Broadband On-Chip Interferometer. For That, Molokai Will Collaborate Closely With Ibsen Photonics, A Spectrometer Company, To Make High-Resolution Spectrometers That Can Be Used To Read Out Bragg Sensors In Fibers.
Next, The Dual-Comb Technology Will Be Ported To A Gaas-On-Silicon Nitride Platform. Here Dual-Comb Systems Allow For The Prospect Of High-Resolution Images.
