Deep Micro-Dictionary Learning and Coding Network

Yan Yan, Wei Wang, Wei Xiao

In this paper, we propose a novel Deep Micro-Dictionary Learning and Coding Network (DDLCN). DDLCN has most of the standard deep learning layers (pooling, fully, connected, input/output, etc.) but the main difference is that the fundamental convolutional l ...

Dual Generator Generative Adversarial Networks for Multi-domain Image-to-Image Translation

Yan Yan, Wei Wang

State-of-the-art methods for image-to-image translation with Generative Adversarial Networks (GANs) can learn a mapping from one domain to another domain using unpaired image data. However, these methods require the training of one specific model for every ...

Cycle In Cycle Generative Adversarial Networks for Keypoint-Guided Image Generation

Yan Yan, Gaowen Liu, Wei Wang

In this work, we propose a novel Cycle In Cycle Generative Adversarial Network (C2GAN) for the task of keypoint-guided image generation. The proposed C2GAN is a cross-modal framework exploring a joint exploitation of the keypoint and the image data in an i ...

GestureGAN for Hand Gesture-to-Gesture Translation in the Wild

Yan Yan, Wei Wang

Hand gesture-to-gesture translation in the wild is a challenging task since hand gestures can have arbitrary poses, sizes, locations and self-occlusions. Therefore, this task requires a high-level understanding of the mapping between the input source gestu ...

Tunable insertion of multiple lines into a Kerr frequency comb using electro-optical modulators

Yan Yan, Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Amirhossein Mohajerin Ariaei, Arne Kordts, Maxim Karpov, Ahmad Fallahpour, Cong Liu, Lin Zhang

We experimentally insert a flexible number of electro-optical (EO) comb lines into a Kerr frequency comb via EO modulation and demonstrate the use of combined Kerr and EO combs as light sources in coherent communications. The number of EO lines inserted in ...

Dual-pump generation of high-coherence primary Kerr combs with multiple sub-lines

Yan Yan, Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Amirhossein Mohajerin Ariaei, Arne Kordts, Long Li, Maxim Karpov, Lin Zhang

We experimentally generate high-coherence primary Kerr combs with multiple sub-lines by using dual pumps and demonstrate the application of a primary comb state in multichannel communications. We find that more than 10 primary comb lines can be generated w ...

Demonstration of optical multicasting using Kerr frequency comb lines

Yan Yan, Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Amirhossein Mohajerin Ariaei, Arne Kordts, Long Li, Maxim Karpov, Zhe Zhao, Lin Zhang

We experimentally demonstrate optical multicasting using Kerr frequency combs generated from a Si3N4 microresonator. We obtain Kerr combs in two states with different noise properties by varying the pump wavelength in the resonator and investigate the effe ...

Wavelength and Pump Power Characterization of Low-phase-noise Kerr Frequency Comb Lines

Yan Yan, Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Maxim Karpov, Lin Zhang

We characterize a low-phase-noise Kerr frequency comb for carrying data channels. Results show pump wavelength detuning region grows slightly at higher pump power and the phase noise stays relatively unchanged over pump wavelength detuning region. ...
