Photonic-Assisted Reconfigurable LO Harmonic Downconverter With RF Self-Inter…

A photonic-assisted reconfigurable LO harmonic downconverter with simultaneous image-rejection and RF self-interference cancellation (SIC) for in-band full-duplex communication is proposed and expe…

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…

Increased Spurious-Free Dynamic Range in Frequency Sweeping Interferometry by…

We propose an envelope detrending method to correct parasitic amplitude modulation (AM) in frequency sweeping interferometry (FSI). Parasitic AM arises from effects such as device spectral response…

Survey on the Analysis and Modeling of Visual Kinship : A Decade in the Making

Kinship recognition is a challenging problem with many practical applications. With much progress and milestones having been reached after ten years, we are now able to survey the research and crea…

Hardware-Efficient Blind Frequency Offset Estimation for Spectral-Efficient D…

For the digital subcarriermultiplexing (DSM) transmission, it is compulsory to realize the frequency offset estimation (FOE) and compensation (FOC) before the subcarrier de-multiplexing and the chr…

Self-Assembled Highly Sensitive Hybrid Structure Sensor for Vector Curvature …

A highly sensitive hybrid structure sensor based on suspended-core fiber (SCF) is proposed for vector curvature and temperature measurement. The sensor is prepared by self-assembly of SCF-based cas…

Advanced DSP Enabled C-Band 112 Gbit/s/λ PAM-4 Transmissions With Severe Ban…

The performance of high-speed intensity modulation direct detection (IM-DD) transmissions is severely degraded by the linear inter-symbol interference (ISI), due to both bandwidth-constrained optoe…

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…

Third-Order-Reflective Hybrid Interleaver Based on Fabry-Perot Assisted Miche…

We present the design and experimental demonstration of a 3rd-order-reflective hybrid interleaver based on Fabry-Perot (FP) cavity assisted Michelson interferometer (FPA-MI), in which the FP cavity…
