Recent advances in neuromorphic computing have established a computational framework
that removes the processor-memory bottleneck evident in traditional von Neumann …

The rapid development of photonic integrated circuits demands the design of efficient and
compact waveguide devices such as waveguide tapers and crossings. Some components in …

While compact and low-loss optical coupling to ultrahigh-quality-factor (Q) crystalline
resonators is important for a wide range of applications, the major challenge for achieving …

This paper reports the first experimental demonstration of silicon photonic (SiPh) Flex-
LIONS, a bandwidth-reconfigurable SiPh switching fabric based on wavelength routing in …

Complex photonic-integrated circuits (PIC) may have strongly non-planar topologies that
require waveguide crossings (WGX) when realized in single-layer integration platforms. The …

We design, fabricate, and demonstrate a low-loss and broadband optical interposer with
high misalignment tolerance for large-scale integration of many chips using thermal …

Valley‐Hall phases, first proposed in 2D materials, originate from nontrivial topologies
around valleys which denote local extrema in momentum space. Since they have been …

We present a 3D integrated wavelength demultiplexer using a square-core fiber (SCF) and
matched dual-layer arrayed waveguide gratings (AWGs). The SCF works as a 3D fiber …

We demonstrate four-wave mixing (FWM) interactions in a-Si: H waveguides in a multilayer
integrated silicon photonic chip. The a-Si: H waveguides are accessed through interlayer …

In this paper, we propose and fabricated a novel scheme of SOI-based 1× 3 coupler with
variable splitting ratio. The coupler consists of two cascaded MMI with different sizes, and a …
