Magnetically controllable multimode interference in topological photonic crystals [PDF]
Light: Science & ApplicationsTopological photonic insulators show promise for applications in compact integrated photonic circuits due to their ability to transport light robustly through sharp bendings. The number of topological edge states relies on the difference between the bulk

Multimode Hong-Ou-Mandel interference [PDF]
Physical Review Letters, 2002 We consider multimode two-photon interference at a beam splitter by photons created by spontaneous parametric down-conversion. The resulting interference pattern is shown to depend upon the transverse spatial symmetry of the pump beam.

Multimode interference dynamic light scattering. [PDF]
Opt Lett, 2018 When dealing with dynamic scattering systems, being able to collect strong signals while maintaining a high signal-to-noise ratio (SNR) is critical. It is well known that a spatially coherent measurement provides the largest SNR, while a partially coherent one provides better means for proper spatial averaging.

Optimized Multimode Interference Fiber Based Refractometer in A Reflective Interrogation Scheme [PDF]
Proceedings, 2018 A fiber based refractometer in a reflective interrogation scheme is investigated and optimized. A thin gold film was deposited on the tip of a coreless fiber section, which is spliced with a single mode fiber. The coreless fiber is a multimode waveguide,

Non-Hermitian multimode interference
Optics Letters, 2020 Multimode interference (MMI) and self-imaging are important phenomena of diffractive optics with major applications in signal processing, beam shaping, and optical sensing. Such phenomena generally arise from interference of normal modes in lossless dielectric guiding structures; however, the impact of spatially inhomogeneous optical gain and loss ...
