Synchronization of Two Microwave Sources With Femtosecond-level Residual Timi…

A microwave photonic phase detector (MPPD) for simultaneous synchronization of two independent microwave sources to a single mode-locked laser (MLL) with femtosecond-level residual timing jitters i…

Over 100 nm Bandwidth Orbital Angular Momentum Modes Amplification For MDM an…

We designed and fabricated a ring-core Bi/Er co-doped fiber (RC-BEDF), and thus investigated the broad-spectrum amplification of orbital angular momentum (OAM) modes. The deviation from the average…

Open-Path Ghost Spectroscopy Based on Hadamard Modulation

In order to achieve spectral detection in free space, an open-path ghost spectroscopy (GS) based on complementary Hadamard modulation is proposed. In the proposed system, a programmable spectral fi…

Learning Spatially Variant Linear Representation Models for Joint Filtering

Joint filtering mainly uses an additional guidance image as a prior and transfers its structures to the target image in the filtering process. Different from existing approaches that rely on local …

Theoretical Analysis of ESA-Enhanced 2.8 μm Lasing in Er-Doped ZBLAN Fiber L…

A detailed analysis of theexcited state absorption (ESA) transition 4 I 13/2 → 4 I 9/2 which occurs in erbium (Er) doped ZBLAN fiber lasers is performed through numerical modeling. It is found th…

Over 100 mW Stable Low-Noise Single-Frequency Ring-Cavity Fiber Laser Based o…

Two kinds of Yb-doped fibers were fabricated, namely, Yb: YAG crystal-derived silica fibers (YCDSFs) with a gain coefficient of 6.0 dB/cm, and Bi/Er/Yb co-doped silica fibers having a Yb concentrat…

Microwave Omnidirectional Angle-of-Arrival Measurement based on an Optical Te…

A photonics-based scheme to measure microwave omnidirectional angle-of-arrival (AOA) is proposed. In the proposed system, an optical carrier is split into two branches. In one branch, the optical c…

Scheduling Virtual Network Reconfigurations in Parallel in Hybrid Optical/Ele…

A hybrid optical/electrical datacenter network (HOE-DCN) integrates the benefits of electrical packet switching (EPS) and optical circuit switching (OCS) for better architectural scalability. Meanw…
