“…Two waveguides will exchange power and become coupled if they are close enough to each other. The amount of exchanged powers depends on the direction of the propagation [15], and we connected the input Ybranch to the two output Y-branches by utilizing the mode coupling phenomena to obtain a 1x4 optical power divider. The spatial dependence of one mode in a waveguide will be modified by another near it, and the optical power transfer from one waveguide to another has efficiency expressed by the coupling coefficient κ [33].…”

Optical communications are identified as a technology that is able to meet future demands. As a passive component of optical communication, optical power dividers play an essential role. We propose a novel 1x4 optical power divider design, which is a combination of an optical power divider design using a Y-branch and an optical power divider using rectangular waveguides utilizing mode coupling phenomena from our previous researched designs. The 1x4 optical power divider design using three Y-branches and utilizing mode coupling phenomena is described in this work. The design consists of three sections: an input Y-branch, rectangular waveguides, and two output Ybranches. By utilizing mode coupling phenomena with 3 rectangular waveguides, the optical power was transferred from one waveguide to its adjacent, so we obtained a wider splitting angle at the input Y-branch. The design was optimized using the beam propagation method (BPM) at a wavelength for optical communication of λ = 1.55 µm. We optimized various parameters such as the width and thickness of the waveguide, splitting angles, coupling gaps, and coupling lengths by doing numerous experiments. The result shows that the proposed design was successfully split into four outputs with 0.14 dB power imbalance at four output ports and 0.12 dB excess loss through the design. The excess loss and power imbalance at varied wavelengths were also observed. The distribution of excess loss and power imbalance is almost stable through the C-band range (1530-1565 nm). The proposed design shows the possibility of a new wide-angle optical power divider design and demonstrates the development possibilities of optical interconnections at wavelengths of 1530-1565 nm.

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
