Enhanced Directional Coupling of Light with a Whispering Gallery Microcavity
Fuchuan Lei, Georgiy Tkachenko, Xuefeng Jiang +3
Directional coupling of light in nanophotonic circuits has recently attracted increasing interest, with numerous experimental realizations based on broken rotational or mirror symm…
Polarization-Controlled Cavity Input-Output Relations
Fuchuan Lei, Jonathan M. Ward, Priscila Romagnoli +1
Cavity input-output relations (CIORs) describe a universal formalism relating each of the far-field amplitudes outside the cavity to the internal cavity fields. Conventionally, the…
Complete polarization control for a nanofiber waveguide using directional coupling
Fuchuan Lei, Georgiy Tkachenko, Jonathan M. Ward +1
Optical nanofiber waveguides are widely used for near-field delivery and measurement of light. Despite their versatility and efficiency, nanofibers have a critical drawback - their…
Raman Laser Switching Induced by Cascaded Light Scattering
Sho Kasumie, Fuchuan Lei, Jonathan M Ward +3
We show that, in multimode Raman lasers, cascaded light scattering (CLS) not only extends the optical frequency range, but could also modulate the laser dynamics. The origin of thi…
Excitation of whispering gallery modes with a "point-and-play", fiber-based, optical nano-antenna
Jonathan M. Ward, Fuchuan Lei, Stephy Vincent +4
We demonstrate the excitation and detection of whispering gallery modes in optical microresonators using a "point-and-play", fiber-based, optical nano-antenna. The coupling mechani…
