Experimental realization of a CMOS-compatible optical directed priority encoder using cascaded micro-ring resonators

Nanophotonics, 2018
In this paper, we propose and experimentally demonstrate an integrated optical device that can implement the logical function of priority encoding from a 4-bit electrical signal to a 2-bit optical signal.

Experimental Verification of Degenerate Band Edge Dispersion in Silicon Photonic Integrated Circuits

IEEE Photonics Journal, 2016
On resonance, periodic dielectric media of finite length exhibit large and distributed internal electric field distributions. The large and distributed fields have been exploited for applications in light emission, optical switching, and nonlinear optics.

Device equivalence in integrated optics [PDF]

Journal of Lightwave Technology, 1995
The concept of device equivalence is introduced. In equivalent devices, the light propagation can be described by identically evolving modal expansions, resulting in identical power transfer ratios. By first applying this concept to a z-invariant structure with a low refractive-index contrast it is shown how a normalized coordinate space can be defined

On-Chip High-Finesse Fabry-Perot Microcavities for Optical Sensing and Quantum Information

Sensors, 2017
For applications in sensing and cavity-based quantum computing and metrology, open-access Fabry-Perot cavities—with an air or vacuum gap between a pair of high reflectance mirrors—offer important advantages compared to other types of microcavities.

Silicon Waveguide Optical Isolator with Directly Bonded Magneto-Optical Garnet

Applied Sciences, 2019
Silicon waveguide optical isolators were fabricated by direct bonding of magneto-optical (MO) garnet. The technique allowed efficient MO phase shift owing to the use of single-crystalline garnet and negligibly thin interlayer on the silicon core layer. A
