“…However, the much smaller wavelength of optical signals leads to a much more challenging fabrication process. For the time being, different types of optical antennas have been demonstrated, including dipole antennas [74,213,154], bow-tie antennas [108,145,241], Yagi-uda antennas [63,112], slot-antennas [44,81,159,240], patch antennas [66,234] and cross-antennas [31]. The fabrication of the majority of these antennas involves the use of Focused Ion-Beam (FIB) milling or Electron Beam Lithography (EBL) and some even newer and more precise nano-fabrication methods.…”

Light(i.e. an optical signal) in its physical nature is an electromagnetic wave at a very high frequency and with a very small wavelength capable of interacting with micro and nano-scale structures. Leveraging these properties of optical signals at nano-scale, we can design nano-systems for actuation and sensing that could enable next generation of human-machine interfaces, medical treatment procedures or next generation of sensing technologies. In this dissertation, we have connected these technological advances in optical communication and merged them with the state of art bio-actuation technologies such as optogenetics and optogenomics, and state of art nano-sensing technologies such as plasmonic sensing. We achieve this by leveraging the advances made in the nanotechnology, nano-communication over the last decade and utilizing the material properties at nano-scale high-frequency designs. First, we present the design, analysis and experimental results of such systems to support optogenetic excitation at cellular level resolution along with the optogenomic excitation. Then, we present the communication channel models for communications to the plasmonic sensing implants using optical frequencies with the strategies to overcome the channel losses. In addition, we present the design and architecture of the optical beam forming system to dynamically steer optical signals that can target the sensing and actuation applications and enable precise control at excitation, reflection and reception of optical signals. At the end, we present a novel concept of joint sensing and communication using plasmonic nano-antennas along with a detailed analysis of excitation waveform, detection methods and communication performance.xiii
