Metamaterial integrated photonics
* Pavel Cheben, National Research Council Canada, Canada Metamaterial engineering has solidified its position as a crucial technology in integrated photonics [1-7]. In this keynote presentation we will review this rapidly advancing field. |

Hybrid tellurite glass-silicon devices for photonic integrated circuits
* Jonathan Bradley, McMaster University, Canada In this talk we describe novel monolithic hybrid integration approaches and waveguide designs for functional glass claddings on silicon-on-insulator. We present our results on low-loss hybrid tellurite-silicon waveguides, high-Q resonators, and amplifiers and lasers and our recent efforts to optimize their performance and utility in silicon photonic systems. |

Implementing a PIC Using Commercial PDKs for Optoelectronic Oscillator Comb Laser Generator
* Ahmad Atieh, Optiwave Systems Inc, Canada OptiSystem, OptiSPICE, OptiFDTD and OptiMode software packages are used to implement photonic integrated circuit (PIC) for optical comb generator. Standard process design kits (PDK) for components based on SOI platform are used in simulating different devices in an optoelectronic oscillator comb laser generator. The comb source has eighty-nine lines and 50GHz free-spectral range. |

Exploring nonlinear effects in InP/InGaAsP platform in the telecom range
* Lais Fujii dos Santos, University of Ottawa, Canada Ozan William Oner, University of Ottawa, Canada Athulya Thulaseedharan, University of Ottawa, Canada Ehsan Mobini, University of Ottawa Kaustubh Vyas, University of Ottawa Gabriel Flizikowski, University of Ottawa, Canada Ksenia Dolgaleva, University of Ottawa, Canada We investigate the occurrence of four-wave mixing (FWM) in InP/InGaAsP waveguides (experimentally and theoretically) and InGaAsP-on-insulator ring resonators (theoretically). Despite the pronounced nonlinear losses in the S and C telecom bands, it was possible to observe FWM in InP/InGaAsP waveguides. The occurrence of FWM in the microrings is limited by the free-carrier lifetime. |

Measuring the Quantum Yield of Silicon using SiPMs
* Harry Lewis, TRIUMF, Canada Nicholas Morrison, TRIUMF, Canada Mahsa Mahtab, TRIUMF, Canada Fabrice Retière, TRIUMF Giacomo Gallina, Princeton University Nicolas Massacret, TRIUMF Peter Margetak, TRIUMF Lars Martin, TRIUMF Andrea Capra, TRIUMF Ryan Underwood, TRIUMF Maia Henriksson-Ward, TRIUMF The quantum yield of silicon as a function of wavelength has been calculated by two different and novel methods using silicon photomultipliers. These methods respectively employ counting photon detection events at the waveform level and using the average photocurrent in different modes of operation of the device. Results using these two methods match and are lower than previously reported. Measurements have been taken at wavelengths of 160-380nm and temperatures down to 183K. Increase in quantum yield with temperature is observed. |

Reference-Based Wavefront Sensing and Correction Using Integrated Photonics Platform
* Aydin Amini, McMaster University, Canada Alexander Parent, McMaster University, Canada Steve Hranilovic, McMaster University, Canada Rafael Kleiman, McMaster University, Canada We present a proof of concept for an integrated photonic interface designed to address the challenge of atmospheric turbulence affecting the optical wavefront in satellite-to-ground downlinks. We demonstrate the potential of a silicon photonic circuit with on-chip sensors as an optically transparent coherent receiver with high correction bandwidth. The proposed chip is equipped with the most compact array of antennas to date for effective wavefront sampling. Our results indicate that the proposed system effectively recovers the signal when the number of on-chip antennas is equal to or exceeds the number of turbulent coherent cells across the wavefront |
