Large grain Ge growth on amorphous substrates for CMOS back-end-of-line integration of active optoelectronic devices
… could be fabricated in the back-end, optical coupling to devices was addressed. For dense three-dimensional integration of photonic devices, vertical coupling between photonic planes is necessary. Therefore, this thesis begins with the design and simulation of vertical couplers. These couplers …

Theory and fabrication of evanescently-coupled photoluminescent devices
… discusses the theory and implementation of evanescently-coupled photoluminescent devices. We demonstrate the feasibility of efficient, spectrally tunable lighting devices through quantum dot photoluminescence. Devices that enjoy both great efficiencies and excellent color temperatures are …

Photonic integrated circuits for optical logic applications
… at 1550 nm for the SOAs, as well as verifying evanescent coupling between the active and passive waveguides. In addition to the vertical integration of photonic waveguides, Esaki tunnel junctions are investigated for vertical electronic integration. Quantum dot formation and growth via …

Photonic Integrated Circuit Packaging Using Silicon Based Optical Interconnects
… of the output PIC waveguide, high intrinsic coupling efficiency, wide alignment tolerances, CMOS compatibility, and scalability to mass manufacturing. Following this will be the description of the adiabatic, inverse SiₓOᵧN subscript z cross tapers which provide vertical evanescent coupling of …

Radiation Pressure induced Nonlinearity in Micro-droplet
… it is possible to achieve highly nonlinear coupling between light and liquid that can potentially lead to single-photon level optical nonlinearity. Specifically, we experimentally characterize a droplet (D~500um) of index matching fluid submerged in the water as a high-Q optical resonator, …

Development of optomechanofluidic resonators
… the response of the system with a single evanescently-coupled tapered optical fibre is employed. This hybrid dual-resonant system consisting of an OMFR shell and contained fluid can be considered a radiation-pressure driven acoustic resonator. The optical modes do not significantly …
