Ultra-compact, densely integrated optical components manufactured on a CMOS-foundry
platform are highly desirable for optical information processing and electronic-photonic co …

Integrating microelectromechanical systems (MEMS) actuators with low-loss suspended
silicon nitride waveguides enables the precise alignment of these waveguides to other …

We experimentally demonstrate a silicon photonic chip-scale 16-channel wavelength
division multiplexer (WDM) operating in the O-band. The silicon photonic chip consists of a …

Bragg filters are of essential importance for chip-scale photonic systems. However, the
implementation of filters with sub-nanometer bandwidth and rejection beyond 70 dB is …

An ultracompact, bandwidth-tunable filter has been demonstrated using a silicon-on-
insulator (SOI) wafer. The device is based on cascaded grating-assisted contra-directional …

We present an analytical simulation and thermal control scheme for a pitch-chirped Contra-
Directional Coupler, able to achieve a 5-nm bandwidth-tunability range for a C-band …

We present a detailed design-space exploration for silicon photonic contra-directional
couplers (CDCs) with sub-wavelength and waveguide gratings, considering similar and …

In this paper, a high-performance electro-optical tunable grating-assisted directional coupler
(GADC) is proposed and demonstrated experimentally. Our proposed GADC consists of a …

We propose and demonstrate a novel two-mode grating assisted contra-directional coupler
(TGACC), which is capable of filtering two modes channels simultaneously by superposed …

A polymer/silica hybrid integration add-drop filter based on a grating-assisted
contradirectional coupler fabricated through simple and low-cost contact lithography is …
