Silicon photonics has experienced phenomenal transformations over the last decade. In this
paper, we present some of the notable advances in silicon-based passive and active optical …

We experimentally demonstrate a compact broadband polarization beam splitter (PBS)
based on a multimode interference (MMI) coupler with internal photonic crystal (PC) for the …

Switching can be performed with multiple physical dimensions of an optical signal.
Previously optical switching was mainly focused in the wavelength domain. In this paper we …

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

Optical switches are key components for routing of light transmission paths in data links.
Existing waveguide-based Mach-Zehnder interferometer (MZI) switches occupy a significant …

In this article, we design a low-loss, high-bandwidth Z-bend photonic silicon crystal
waveguide bending in a triangular lattice through topology optimization. Based on the …

In this paper we study slot structures in the 120° photonic crystal waveguide (PCW) bends.
We find that the transmission characteristics of the slotted PCW bend can be simply …

The two-dimensional high-temperature superconducting photonic crystal structure has been
widely studied as a novel type of photonic crystal structure. This paper investigates the …

We demonstrate electro-optical tuning of degenerate band edge resonances in Si photonic
waveguides for applications including tunable filters, low voltage switches, and modulators …

A compact (15µm× 15µm) and highly-optimized 2× 2 optical switch is demonstrated on a
CMOS-compatible photonic crystal technology. On-chip insertion loss are below 1 dB, static …
