10th Anniversary of LSA: Collection on Nonlinear Optics and Ultrafast Optics
2022 marks the 10th anniversary of Light: Science & Applications (LSA). In the past decade, LSA has published hundreds of outstanding researches covering the fundamentals and applications in all areas of optics and photonics. From those published papers, we have picked some on Nonlinear Optics and Ultrafast Optics to share with you, our readers. We hope this collection can stimulate more researches and practices in related fields, and promote further progress in optics and photonics research.
The fiber birefringence, chromatic dispersion, and nonlinear effect follow a phase-matching principle, enabling the formation of birefringence-managed solitons in normal-dispersion fiber lasers containing a section of polarization-maintaining fiber.
A widely tunable phase-matched second harmonic generation (221–332 nm) covering almost the entire deep-UV spectral range is experimentally realized by angular engineering strategy of an additional periodic phase.
Laser pulses generate pressure waves due to electrostriction effects decoupling bulk and boundary optical forces in water, probed by the convoluted optical signal due to the resulting spatiotemporal pressure distribution.
We demonstrate a new strategy for recording THz electric signals with long duration and high bandwidth. It uses an original combination of Terahertz electro-optic detection techniques, with diversity concepts borrowed from wireless communications and time-stretch.
We demonstrate that plexcitons in monolayer semiconductors sustain giant nonlinearity at room temperature and thus very hopeful to realize the practical implementation of polaritonic devices.
Ultrafast low-pump fluence all-optical modulation for near and mid-infrared wavelengths is demonstrated by enhancing the interaction between graphene and pump/probe light in the nanoscale “hot spots” of graphene-plasmonic hybrid metasurfaces.
We generate extremely asymmetric sub-half-cycle terahertz waveforms with scalable field strengths at megahertz pulse-repetition rates via ultrafast excitation of spatially indirect interband transitions in tailored quantum well heterostructures.
We introduce and experimentally demonstrate a novel technique for the complete characterization of ultrafast optical fields based on phase-preserving nonlinear interferometric autocorrelation without any spectroscopic measurements.
A novel attosecond-scale streaking method was proposed and demonstrated to determine the tunneling time of an electron with a precision of a few attoseconds.
Coherent all-optical modulation of nonlinear optics with chiral light in symmetrical crystals is achieved with ultra-fast speed (~ fs), unlimited bandwidth, perfect modulation depth (~100%), and compact footprint (atomic thickness).
We observe the error rate threshold of quantum fault-tolerant computation by using optical spatial modes of two entangled photons to encode logical qubits.
Two-dimensional terahertz strong-field spectroscopy reveals wave-mixing processes up to eighth order in a free-running quantum cascade laser, unraveling its sub-cycle gain dynamics and nonlinearities in a regime of negative absorption.
