Interconnection network architectures based on integrated orbital angular momentum emitters [PDF]

, 2018
Novel architectures for two-layer interconnection networks based on concentric OAM emitters are presented. A scalability analysis is done in terms of devices characteristics, power budget and optical signal to noise ratio by exploiting experimentally ...

Multi-Carrier Coherent Receiver Based on a Shared Optical Hybrid and a Cyclic AWG Array for Terabit/s Optical Transmission

IEEE Photonics Journal, 2010
We describe a multi-carrier coherent-receiver scheme where the coherent beating between an ultra-high-speed multi-carrier signal and multiple optical local oscillators (OLOs) is conducted in a single optical hybrid, followed by carrier separation through

Ultra-Wideband RF-Photonics Technology for Microwave Spectrometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
We describe an RF-photonic system architecture to measure microwave spectrum over a wide bandwidth with high resolution. The approach relies on the up-conversion of the electronic signal to the optical domain using a high-speed electro-optic modulator ...

Si-Ge-Silica Monolithic Integration Platform and Its Application to a 22-Gb/s $\times$ 16-ch WDM Receiver

IEEE Photonics Journal, 2013
We describe a Si-Ge-silica monolithic integration platform for telecommunications applications. The monolithic integration process features low-temperature silica film deposition by electron-cyclotron-resonance chemical vapor deposition to prevent ...

Compact and Flexible on-Chip Spectrometer Based on Metalens-Assisted Arrayed Waveguide Grating

IEEE Photonics Journal
To address the trade-off between footprint and spectral performance in on-chip spectrometers, this paper presents a compact and flexible on-chip metalens-assisted arrayed waveguide grating (AWG) spectrometer. By integrating an on-chip metalens within the

Eight-Wavelength Selectable Single-Longitudinal- Mode Fiber Laser Using 1× 8 Arrayed Waveguide Grating and Passive Triple Subring Resonators

IEEE Photonics Journal
In this paper, we demonstrate a stable output single-longitudinal-mode (SLM) Erbium-doped fiber laser (EDFL) with eight selectable wavelengths. The EDFL achieves wavelength selection through a 1 × 8 arrayed waveguide grating (AWG) and generates ...
