TD-1-26-1 / Exploring a Silicon on Insulator based Integrated Optical Chip for Interferometric Fiber Optic Gyroscopes
* Akash Chauhan, York University , Canada
Hugh Podmore, York University
Regina Lee, York University
We develop a Silicon on Insulator based integrated optical chip for Interferometric Fiber Optic Gyroscopes. The optical design mirrors what is being done in literature, however some differentiating factors include: the introduction of a polarization filter and the choice of waveguide technology. The polarization filter alongside the grating couplers will result in a polarization extinction ratio of >76 dB at the detector. Silicon on Insulator was chosen because advances in Silicon photonics for IFOGs may enable cheaper fabrication and all-in-one integration of signal processing electronics and optical circuitry on a single chip.

TD-1-26-3 / International Photonic Systems Roadmap: the System-in-a-Package Paradigm for 21st Century Applications
* Sajan Saini, Massachusetts Institute of Technology, United States
Lionel Kimerling, Massachusetts Institute of Technology
Electronic-photonic integration is a system-level scaling solution to improve cost, power efficiency, bandwidth density, and time to market for datacom, wireless, sensing, and imaging applications. The International Photonic Systems Roadmap (IPSR-I) has identified a growing disparity between customized photonics and commoditized electronics as a limiting barrier to breakthrough E-P co-design. Datacom E-P co-design for data centers and in-vehicle networks indicate how (i) component performance will scale with integration; and (ii) parallelism leads to novel architectural scaling, such as the system-in-a-package. Implications for 5G wireless and augmented reality imaging will be briefly considered.
TD-1-26-4 / Thin film amorphous oxides for photonics structures
* Carmen S. Menoni, Colorado State University, United States
Thin film amorphous oxides deposited by physical vapor deposition are the backbone of multilayer nterference coatings (IC), ubiquitous in laser systems. These multilayer structures consist of a stacks of non-absorbing amorphous oxides designed to have a specific optical response over a desired wavelength range. IC technology is fully developed and supports a multi-million dollar industry. Nevertheless, there are new challenges ICs face in advanced optical systems. In this talk I will discuss how an IC is designed and grown. I will also describe how these thin film optical structures are characterized. The focus of this talk will be on two specific examples: ICs for high intensity near infrared lasers and IC for ultra-stable interferometric cavities. Improving IC performance in the former relies on understanding the interaction of the materials with high energy laser pulses ranging from picosecond to femtosecond duration. In the latter, the aim is to identify materials modifications that can reduce internal friction.
TD-1-26-5 / Quasinormal Mode Theory of Mechanical Cavity Resonances on Optomechanical Beams
* Al-Waleed El-Sayed, Queen's University, Canada
Stephen Hughes, Queen's University
The use of cavity mode theories is less developed in mechanics than in optics. A quasinormal mode theory of mechanical open-cavity modes is introduced and used to demonstrate the importance of using a generalized effective mode volume and the phase of the quasinormal mode. Consequently, we introduce a rigorous description of the elastic Purcell factor and Fano resonances of coupled cavity structures.
