Magnon polaron formed by selectively coupled coherent magnon and phonon modes of a surface patterned ferromagnet (2020)
Journal Article

Strong coupling between two quanta of different excitations leads to the formation of a hybridized state which paves a way for exploiting new degrees of freedom to control phenomena with high efficiency and precision. A magnon polaron is the hybridiz... Read More about Magnon polaron formed by selectively coupled coherent magnon and phonon modes of a surface patterned ferromagnet.

Temporal superoscillation of sub-terahertz coherent acoustic phonons (2020)
Journal Article

We observe coherent acoustic phonon superoscillations at sub-terahertz frequencies. The superoscillations result from the interference of optically excited coherent longitudinal acoustic phonon modes in a GaAs/AlGaAs superlattice. The superoscillatio...

Temporal superoscillations of subterahertz coherent acoustic phonons (2020)
Journal Article

We observe coherent acoustic phonon superoscillations at subterahertz frequencies. The superoscillations result from the interference of optically excited coherent longitudinal acoustic phonon modes in a GaAs/AlGaAs superlattice. The superoscillation...

Large non-thermal contribution to picosecond strain pulse generation using the photo-induced phase transition in VO2 (2020)
Journal Article

Picosecond strain pulses are a versatile tool for investigation of mechanical properties of meso-and nano-scale objects with high temporal and spatial resolutions. Generation of such pulses is traditionally realized via ultrafast laser excitation of...

High-speed modulation of a terahertz quantum cascade laser by coherent acoustic phonon pulses (2020)
Journal Article

The fast modulation of lasers is a fundamental requirement for applications in optical communications, high-resolution spectroscopy and metrology. In the terahertz-frequency range, the quantum-cascade laser (QCL) is a high-power source with the poten...
