The mode-division-multiplexing (MDM) technology has become an alternative solution to
further increase the link capacity in optical communication systems. Ultralow loss waveguide …

We observe that the cascaded typical Y junctions will introduce unwanted periodic fringes
over the spectrum in practical systems when they link with multimode waveguides. To solve …

We propose and experimentally demonstrate a novel ultracompact dual-mode waveguide
crossing based on subwavelength multimode-interference couplers for a densely integrated …

We theoretically propose and experimentally demonstrate a novel ultra-compact four-mode
silicon waveguide crossing device based on the asymmetric directional couplers for densely …

A low loss, small crosstalk offset crossing structure for a Si wire waveguide is proposed. We
analyzed the properties of the structure for both the TE and TM modes by 2-D FDTD (two …

We design, fabricate, and characterize a compact dual-mode waveguide crossing on a
silicon-on-insulator platform. The dual-mode waveguide crossing with high performance is …

A dual-mode waveguide crossing is proposed and realized for the application of on-chip
multimode interconnection. The present structure is realized by two 90° crossed multimode …

A low-loss and low-crosstalk multimode waveguide bend is proposed and demonstrated for
mode-division-multiplexed optical interconnects. The proposed 90°-bend is composed of …

Multimode waveguide crossings (MWCs) are becoming more and more important as one of
the key elements for on‐chip optical routing and cross‐connection. However, it is still very …

Mode multiplexing technique is a new promising option to increase the transmission
capacity of on-chip optical interconnects. Multimode waveguide crossings are the key …
