Integrated Electro-Optic Isolator on Thin Film Lithium Niobate
Mengjie Yu, Rebecca Cheng, Christian Reimer +9
Optical isolator is an indispensable component of almost any optical system and is used to protect a laser from unwanted reflections for phase-stable coherent operation. The develo…
Systematic Investigation of Millimeter-Wave Optic Modulation Performance in Thin-Film Lithium Niobate
Yiwen Zhang, Linbo Shao, Jingwei Yang +7
Millimeter-wave (mmWave) band (30 - 300 GHz) is an emerging spectrum range for wireless communication, short-range radar and sensor applications. mmWave-optic modulators that could…
Spectral control of nonclassical light using an integrated thin-film lithium niobate modulator
Di Zhu, Changchen Chen, Mengjie Yu +11
Manipulating the frequency and bandwidth of nonclassical light is essential for implementing frequency-encoded/multiplexed quantum computation, communication, and networking protoc…
Femtosecond Pulse Generation via an Integrated Electro-Optic Time Lens
Mengjie Yu, Christian Reimer, David Barton +12
Integrated femtosecond pulse and frequency comb sources are critical components for a wide range of applications. The leading approaches for on-chip pulse generation rely on mode l…
High-efficiency and broadband electro-optic frequency combs enabled by coupled micro-resonators
Yaowen Hu, Mengjie Yu, Brandon Buscaino +8
Developments in integrated photonics have led to stable, compact, and broadband comb generators that support a wide range of applications. Current on-chip comb generators, however,…
Integrated photonics on thin-film lithium niobate
Di Zhu, Linbo Shao, Mengjie Yu +12
Lithium niobate (LN), an outstanding and versatile material, has influenced our daily life for decades: from enabling high-speed optical communications that form the backbone of th…
Reconfigurable electro-optic frequency shifter
Yaowen Hu, Mengjie Yu, Di Zhu +7
Here we demonstrate an on-chip electro-optic frequency shifter that is precisely controlled using only a single-tone microwave signal. This is accomplished by engineering the densi…
Dynamical tunneling-assisted coupling of high-Q deformed microcavities using a free-space beam
Qi-Fan Yang, Xue-Feng Jiang, Ya-Long Cui +2
We investigate the efficient free-space excitation of high-Q resonance modes in deformed microcavities via dynamical tunneling-assisted coupling. A quantum scattering theory is emp…
