Photonic Generation of a Tunable Dual-Chirp Microwave Waveform
A photonic-assisted tunable dual-chirp microwave waveform generator based on optical heterodyne detection is proposed and experimentally demonstrated. In the proposed scheme, a three-electrode dist…
Generalized Domain Conditioned Adaptation Network
Domain adaptation (DA) attempts to transfer knowledge learned in the labeled source domain to the unlabeled but related target domain without requiring large amounts of target supervision. Recent a…
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…
Accelerating LMS-Based Equalization With Correlated Training Sequence in Band…
As higher symbol rates are utilized in the intensity modulation and direct detection (IM/DD) scheme to meet the unrelenting growth of data traffic, overcoming the inter-symbol interference (ISI) in…
Learning to Detect Salient Object With Multi-Source Weak Supervision
High-cost pixel-level annotations makes it appealing to train saliency detection models with weak supervision. However, a single weak supervision source hardly contain enough information to train a…
Dislocation Evolvement in Metamorphic In0.83Ga0.17As/InP Photodetectors Throu…
Ex-situ rapid thermal treatments of 1–2.5 μm extended wavelength In 0.83 Ga 0.17 As/In 0.83 Al 0.17 As photodetector epiwafers on InP substrate were investigated. Enhanced photoluminescence inte…
Modulator Coefficient Tracking Method of Resonant Integrated Optical Gyroscop…
A modulator coefficient tracking system (MCTS) with the novel four-state modulation technique is proposed to improve the stability of scale factor for resonant integrated optical gyroscope (RIOG). …
Complementary Polarization-Diversity Coherent Receiver for Self-Coherent Homo…
There has been renewed interest in coherent detection to provide high spectral efficiency transmission for short-reach optical interconnects. However, the expensive high-stable laser sources may pr…
Prior Guided Feature Enrichment Network for Few-Shot Segmentation
State-of-the-art semantic segmentation methods require sufficient labeled data to achieve good results and hardly work on unseen classes without fine-tuning. Few-shot segmentation is thus proposed …
