Abstract: We design, model, assemble, or measure novel integrated photonic architectural structures using various novel resonators, such as diamond and silicon spheres, or silicon on oxide (SOI)-distributed feedback (DFB) meandering waveguides for potential photonic applications. Spherical optical microcavities are the building blocks of three dimensional photonics, as linear optical microcavities are the building blocks of one dimensional photonics. Dielectric and semiconductor based lightwave circuit elements are being integrated into fiber optics and integrated photonics. Diamond and silicon microspheres lead themselves to various lightwave circuit element applications such as channel dropping filters, tunable filters, and optical modulators using optical fiber half couplers (OFHCs) manufactured from single mode optical fibers or optical waveguides manufactured using femtosecond laser processing. SOI-DFB meandering waveguides, as novel integrated optical elements, can exhibit a variety of spectral responses such as coupled resonator induced transparency filter, Fano resonator, hitless filter, Lorentzian filter, Rabi splitter, self coupled optical waveguide, and tunable power divider. All these novel integrated photonic architectural structures can find information processing applications in quantum circuits for computing and communication.
