This proposal proposes to commercialize the technology, Light Modulated Acoustic Devices (LMAD) to translate basic research on photonic materials from the laboratory to the market place. Controlling sound actively using light is challenging and is considered to be one of the holy grail of acoustics technology due to the fundamental differences in the nature of the acoustic and electromagnetic waves. The PI and his team propose to commercialize the technology to photo-actively control phononic properties remotely using the novel dielectric properties of nanoparticles embedded in phononic crystals. Since phononics deals with vibrations, acoustic or otherwise, potential applications range from active, non-contact vibration dampening for vehicles and devices, to smart, high resolution ultrasound technology, to environmental technologies to actively reduce noise pollution. LMADs are part of the subcategory of technology of photonics, phononics.Greater dynamic flexibility in existing focused-sound technologies will be achieved via this technology. Active selective-filtering element for vibration dampening can be used to filter out selected unwanted vibration modes. Typical customers would consist of manufacturers of ultrasonic equipment for either hyperthermic biomedical, imaging, or structural characterization applications.

该提案建议将光调制声学设备(LMAD)技术商业化，将光子材料的基础研究从实验室转化为市场。由于声波和电磁波性质的根本不同，利用光主动控制声音是具有挑战性的，被认为是声学技术的圣杯之一。PI和他的团队提议将这项技术商业化，利用嵌入声子晶体中的纳米颗粒的新颖介电特性来远程光主动控制声子特性。由于声学涉及振动，无论是声学的还是其他的，潜在的应用范围从车辆和设备的主动、非接触式减振，到智能、高分辨率超声波技术，再到主动减少噪音污染的环境技术。LMAD是光子学、声子学技术的一部分，通过这项技术将在现有的聚焦声音技术中实现更大的动态灵活性。用于减振的有源选择性滤波元件可以用来滤除选定的不需要的振动模式。典型的客户将包括用于高温生物医学、成像或结构表征应用的超声波设备制造商。
