Adiabatic waveguide taper and on-chip wavelength demultiplexer are the key components
of photonic integrated circuits. However, these two kinds of devices which were designed by …

Silicon-based optical switches are integral to on-chip optical interconnects, and mode-
division multiplexing (MDM) technology has enabled modes to function as carriers in …

A Y-junction is commonly used in on-chip systems because of its excellent broadband
characteristic. However, due to the lack of regulation methods, in most cases Y-junctions are …

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 …

To overcome the limitation of dynamic reciprocity, a new method for designing broadband
on-chip optical isolators is proposed and demonstrated based on saturated gain, which is …

The power splitter is a device that splits the energy from an input signal into multiple outputs
with equal or uneven energy. Recently, the use of algorithms to intelligently design silicon …

The Si-based chip-integrated OR, XOR, NOR, AND and NAND all-optical logic gates (AO-
LGs) with footprints of 2 μm× 2 μm are inversely designed based on an intelligent method …

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

In this paper, we demonstrate silicon-on-insulator (SOI) channel waveguides with
propagation loss and= 10 bends with bending loss as low as 2 dB/cm and 0.02 dB/90 in the …

We propose a novel, low-cost bidirectional optical subassembly (BOSA) that uses a single
glass-sealed conventional transistor-outline (TO)-CAN package for passive optical network …
