Sub 100 μm size polarization independent WDM wavelength filters using Si waveguide
2010 Edition, July 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We describe polarization independent wavelength filters using sub-micron Si waveguide. Designs for multistage Mach-Zehnder interferometer, ring resonator, arrayed waveguide grating and multimode interference coupler are reported. The...

Sub-micron Si waveguide design for polarization independent Mach-Zehnder filter
2009 Edition, September 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We report the design for the polarization independent Mach-Zehnder interferometer wavelength filter using sub-micron Si waveguide. The same waveguide cross sections can be used for the directional coupler and phase shifter. A...

Post-Integrated Dual-Core Large-End Spot-Size Converter with Si Vertical Taper for Fiber Butt-Coupling to Si-Photonics Chip
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We experimentally demonstrated a post-integrated dual-core spot-size converter (SSC) that had a coupling end with a 10-μm diameter at the edge of an Si-photonics chip. Although there was an extra loss increase as a result of post-integration, it can be reduced and, thus, the...

2018 Edition, Volume 36, October 15, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We experimentally demonstrated a post-integrated dual-core spot-size converter (SSC) that had a coupling end with a 10-μm diameter at the edge of an Si-photonics chip. Although there was an extra loss increase as a result of post-integration, it can be reduced and, thus, the...

SUMMeR: Sub-Nyquist MIMO Radar
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Multiple input multiple output (MIMO) radar exhibits several advantages with respect to traditional radar array systems in terms of flexibility and performance. However, MIMO radar poses new challenges for both hardware design and digital processing. In particular, achieving high azimuth resolution...

Ring-Resonator-Based Sub-THz Dielectric Sensor
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter presents a design, fabrication, and measurement of a ring-resonator-based subterahertz (sub-THz) dielectric sensor. The sensor consists of a ring-resonator-based notch filter, a sub-THz dielectric waveguide (DWG), and a pair of transitions from the microstrip...

A Cognitive Sub-Nyquist MIMO Radar Prototype
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a cognitive prototype that demonstrates a colocated, frequency-division-multiplexed, multiple-input multiple-output (MIMO) radar which implements both temporal and spatial sub-Nyquist sampling. The signal is sampled and recovered via the Xampling framework. Cognition is due to the...

A Sub-Nyquist Radar Electronic Surveillance System
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The modulated wideband converter (MWC) is well known for a sub-Nyquist wideband sampling capability based on compressed sensing (CS) theory. In this paper, our goal is to use the MWC as a base to design a sub-Nyquist radar electronic surveillance (ES) system. Our focus is then...

Sub-Nyquist Sampling of Multiple Sinusoids
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose new sub-Nyquist sampling schemes for multiple sinusoids, which require fewer number of samples than previous works. Since it is impossible to resolve the frequency ambiguity using a single sub-Nyquist sample sequence, an additional sampling channel is...

Dynamic Similar Sub-Series Selection Method for Time Series Forecasting
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Accumulation of influencing factors during several consecutive time periods makes the variation of target parameters lag behind the variation of their influencing factors. This important phenomenon, known as the cumulative effect, would lead to relatively large forecasting errors. In this paper,...
