Abstract Wavelength-division-multiplexing (WDM) transceiver filters are one of the most
essential components for realizing the fiber-to-the-home (FTTH) networks. In recent years …

We show that the self-imaging principle still holds true in multi-mode photonic crystal (PhC)
line-defect waveguides just as it does in conventional multi-mode waveguides. To observe …

A highly efficient design of a two-channel wavelength demultiplexer in the visible region is

We design and experimentally demonstrate a broadband 1310/1550 nm wavelength
demultiplexer based on a multimode interference coupler with a tapered internal photonic …

Three single-mode photonic crystal waveguides (PCWs) are put together closely to construct
three PCWs directional coupler (3PCWDC). It is found that the coupling coefficient of two …
