Single-shot Kramers-Kronig complex orbital angular momentum spectrum retrieval
Camille Sophie Brès, Jianqi Hu, Yujie Chen
Orbital angular momentum (OAM) spectrum diagnosis is a fundamental building block for diverse OAM-based systems. Among others, the simple on-axis interferometric measurement can retrieve the amplitude and phase information of complex OAM spectra in a few s ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2023Editorial Foreword to The ECOC 2022 Special Issue
Niels Quack, Hans Georg Limberger, Rachel Grange, Christian Bosshard
The European Conference on Optical Communications (ECOC) is one of the leading conferences in the field of optical communications and its related topics. The 48th edition took place from 18th-22nd September 2022 in Basel, Switzerland. The conference attrac ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Tunable acousto-optic optical frequency combs
Examination of various issues related to the generation and application of optical frequency combs (OFCs) is an important branch of modern optoelectronics. Some of the proposed OFC generation methods apply acousto-optic (AO) devices. The AO devices are use ...
Optica Publishing Group2022Tunability of space-time wave packet carrying tunable and dynamically changing OAM value
Tobias Kippenberg, Maxim Karpov, Hao Song, Xinzhou Su
Space-time (ST) wave packets have gained much interest due to their dynamic optical properties. Such wave packets can be generated by synthesizing frequency comb lines, each having multiple complex-weighted spatial modes, to carry dynamically changing orbi ...
Optica Publishing Group2022Spectral self-imaging of optical orbital angular momentum modes
Camille Sophie Brès, Jianqi Hu, Yin Chen, Yujie Chen
The Talbot self-imaging effect is mostly present in the forms of space or time, or in the frequency domain by the Fourier duality. Here, we disclose a new spectral Talbot effect arising in optical orbital angular momentum (OAM) modes. The effect occurs in ...
AIP Publishing2021Photonic chip-based resonant supercontinuum via pulse-driven Kerr microresonator solitons
Tobias Kippenberg, Junqiu Liu, Wenle Weng, Tobias Herr, Miles Henry Anderson
Supercontinuum generation and soliton microcomb formation both represent key techniques for the formation of coherent, ultrabroad optical frequency combs, enabling the RF-to-optical link. Coherent supercontinuum generation typically relies on ultrashort pu ...
OPTICAL SOC AMER2021Reconfigurable radiofrequency filters based on versatile soliton microcombs
Tobias Kippenberg, Camille Sophie Brès, Jianqi Hu, Junqiu Liu, Maxim Karpov, Arslan Sajid Raja, Jijun He, Anton Lukashchuk
The rapidly maturing integrated Kerr microcombs show significant potential for microwave photonics. Yet, state-of-the-art microcomb-based radiofrequency filters have required programmable pulse shapers, which inevitably increase the system cost, footprint, ...
2020Monolithic piezoelectric control of soliton microcombs
Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Erwan Guillaume Albert Lucas, Wenle Weng, Arslan Sajid Raja, Jijun He, Miles Henry Anderson, Tianyi Liu
High-speed actuation of laser frequency(1)is critical in applications using lasers and frequency combs(2,3), and is a prerequisite for phase locking, frequency stabilization and stability transfer among optical carriers. For example, high-bandwidth feedbac ...
NATURE PUBLISHING GROUP2020Broadband quasi-phase-matching in dispersion-engineered all-optically poled silicon nitride waveguides
Tobias Kippenberg, Camille Sophie Brès, Rui Ning Wang, Ozan Yakar, Boris Zabelich, Junqiu Liu, Edgars Nitiss
Quasi-phase-matching (QPM) has become one of the most common approaches for increasing the efficiency of nonlinear three-wave mixing processes in integrated photonic circuits. Here, we provide a study of dispersion engineering of QPM second-harmonic (SH) g ...
2020Frequency division using a soliton-injected semiconductor gain-switched frequency comb
Tobias Kippenberg, Junqiu Liu, Wenle Weng
With optical spectral marks equally spaced by a frequency in the microwave or the radio frequency domain, optical frequency combs have been used not only to synthesize optical frequencies from microwave references but also to generate ultralow-noise microw ...
