Proximal-Only Transmission Matrix Recovery of an Arbitrarily Deformed Graded-Index Multimode Fiber
Cole Reynolds
The multimode fiber is among the thinnest imaging conduits available, carrying hundreds to thousands of spatial modes through a cross-section comparable to a human hair, but its en…

Origin of degenerate bound states in the continuum in a grating waveguide: Parity symmetry breaking due to mode crossing
Cole Reynolds, Vladimir Kocharovsky, Vitaly Kocharovsky
We explain the origin of bound states in the continuum (BICs) in a planar grating waveguide, in particular, a mechanism for formation of degenerate BICs, via the analytical theory…
