Compact lithium niobate photonic integrated circuits
Yan Gao, Fuchuan Lei, Marcello Girardi +4
Lithium niobate (LN) is a promising material for future complex photonic-electronic circuits, with wide applications in fields like communications, sensing, quantum optics, and com…
Integrated, ultra-compact high-Q silicon nitride microresonators for low-repetition-rate soliton microcombs
Zhichao Ye, Fuchuan Lei, Krishna Twayana +3
Multiple applications of relevance in photonics, such as spectrally efficient coherent communications, microwave synthesis or the calibration of astronomical spectrographs, would b…
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…
Polarisation control for optical nanofibres by imaging through a single lens
Georgiy Tkachenko, Fuchuan Lei, Síle Nic Chormaic
We present a simple method for controlling the polarisation state of light at the waist of a single-mode optical nanofibre. The method consists of complete polarisation compensatio…
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…
