Linearly polarized (LP) modes in few-mode fibers are not true eigenmodes but approximated modes constituting of linear combinations of true eigenmodes. Therefore, the vector field profile in a few-mode fiber must be expressed in terms of the true eig

The quadruple series coupled microring resonator (MRR) can realize a boxlike spectral response and lower adjacent channel crosstalk. Utilizing these features, we demonstrated the element of Optical Code Division Multiplexing (OCDM) coding circuit usi

We propose a digital filter design method for a Chebyshev filter based on a high-order microring resonator (MRR). This method enables us to much more easily design an MRR Chebyshev filter with a desired 3 dB wavelength bandwidth and free spectral ran
