About this Research Topic
Optoacoustics is a rapidly developing field of research which explores the interaction between light and ultrasound. Currently experiments in this field focus on micro- and nano-scale systems including, micro-resonators and photonic crystal fibers, amongst others. In order to induce this effect the light intensity must vary, either periodically (modulated light), or as a single flash (pulsed light). The effect could be a result of a plethora of physical mechanisms, such as the photothermal effect, photochemical reactions, electromagnetic radiation, or light scattering, etc. In addition, optoacoustics are now considered to be a prime candidate for realizing quantum interfaces between phonons and photons, with potential applications in quantum information storage, laser cooling, nonreciprocal devices, and novel ultra-narrow linewidth lasers.
Over the past two decades, multi-dimensional photonics has undergone rapid development, owing to the fact that quantum information processing, telecommunications and optical trapping have begun to be implemented exhibiting high-order modes. Despite the fact that the optoacoustic effect (OAE) has been studied extensively in various materials and applied in numerous photonic systems, scaling these systems to integrate high-dimensional photonics remains a significant challenge. In order to further evaluate the OAE and maximize its application in currently emerging technologies, it is imperative to focus on the following areas:
- Understanding how to excite high-order acoustic modes using two optical waves and evaluate the physical mechanisms behind it.
- Understanding how to increase the efficiency exhibited by high-dimensional optoacoustic interactions by changing the mode structures, waveguide structures, and waveguide materials.
- Understanding how to design and apply the multi-dimensional OAE which is applicable across areas widely utilized in the real world.
The scope of this Research Topic aims to provide an open forum to discuss the most recent advances with respect to the study of novel OAEs (novel physical mechanisms, novel materials, or novel structures, etc.) which generally promote its continued development for practical applications. The related themes cover three aspects: fundamentals, systems, and applications. Specific themes in each aspect include but are not limited to:
- Novel OAEs, such as multi-dimensional OAEs;
- Novel materials and structures that transmit exotic light and sound waves;
- Novel technologies to detect light-sound interactions;
- Active and passive devices exhibiting novel OAEs;
- Novel applications utilizing OAE.
