This technology is a method of mitigating propagation losses in high confinement, multimode waveguides.
Chip-based nonlinear photonics applications require robust and compact broadband optical frequency combs. High confinement waveguides are a key component of optical frequency combs. Mitigating propagation losses in high confinement waveguides is critical to achieving low power, broadband frequency combs.
Using a highly multimode structure to shape the fundamental mode, this waveguide design reduces overlap between the fundamental and transverse modes. The reduced overlap alleviates the need for complex fabrication processes and can easily be applied to a variety of materials to create ultralow loss waveguides for low-power, wide-broadband optical frequency combs. This method of improving chip-based photonic devices has applications in optical coherence tomography, high-speed communications, and advanced scientific instrumentation.
By propagating a single mode in multimode microresonators, this technology achieves intrinsic quality factors (Q) of 31.8 ± 4.4 million.
