NL-4-26-1 / Chirped pulsed solitons in nonlinear Kerr resonators
* William Renninger, University of Rochester, United States
Kerr resonators represent a promising alternative to mode-locked lasers for ultrashort pulse generation. Kerr resonators support stable solitons that are useful for a range of applications. Moreover, Kerr resonators are passive cavities without a gain medium that can restrict the performance of mode-locked lasers. In this talk I will discuss recent developments in the generation of ultrashort pulses from fiber Kerr resonators. Specifically, I will introduce new nonlinear wave phenomena in normal dispersion and dispersion-managed cavities, including stable chirped pulses and the shortest pulses observed to date from a fiber Kerr resonator.
NL-4-26-2 / Ultrafast random Raman soliton random bit generator

Using modulation instability, the formation of solitons was experimentally observed in a random Raman fiber laser. The random solitons were then used to generate random bits at up to 240 Gbps, with minimal post-processing.
NL-4-26-3 / Analytic Description of Raman-Induced Frequency Shift of a Soliton
* Robi Kormokar, McGill University, Canada
Martin Rochette, McGill University
We derive an analytic expression for the Raman-induced frequency shift of a fundamental soliton in an optical fiber, beyond the well-known Gordon formula. Resulting from the moment method the expression quantifies the soliton frequency shift as a function of fiber and pulse parameters.
NL-4-26-4 / Connecting widely separated optical frequencies using chip-integrated nonlinear microresonators
* Kartik Srinivasan, NIST, United States
Nonlinear nanophotonic technologies can enable an unprecedented ability to connect regions of the optical spectrum together. In this talk, I will discuss our laboratory’s efforts in developing nonlinear photonic resonators in the silicon nitride platform for both quantum and classical photonic links. I will review the basic design and engineering principles behind these devices, and discuss their application in quantum frequency conversion of single photons, visible-telecom entangled photon pair generation, octave-spanning spectral translation, the generation of visible laser light from near-infrared pump sources, and the use of nonlinear resonators in optical atomic clocks.

A hybrid fiber-integrated mode-locking scheme based on an integrated microring resonator and active modulation is presented. Exploiting nonlinear polarization rotation and active phase modulation enables the generation of on-chip frequency combs, access to higher harmonic mode-locking regimes with a repetition rate of 10.6 MHz, as well as stable long-term operation. With these features, the presented scheme provides a robust and versatile tool for applications in telecommunications and metrology.
NL-4-26-6 / High-performance on-chip Vernier spectrometer
* Zhongjin Lin, Laval University, Canada
Wei Shi, Laval University
We propose and demonstrate a silicon photonic vernier resonator-based spectrometer. With an ultra-compact footprint of 200 * 200 um^2, it simultaneously achieves a high resolution of 0.3 nm and a large bandwidth of 100 nm, consuming ~183 mW for wavelength sweeping across 75 nm.
NL-4-26-7 / GaN waveguides for on-chip quantum sources
* Kaustubh Vyas, University of Ottawa, Canada

This study focuses on design of Gallium Nitride waveguides on two different substrate platforms for correlated photon pair generation
NL-4-26-8 / Towards atomic and picosecond resolution with single-photon sensitivity
* Heidi Miller, Queen's University, Canada
James Godfrey, Queen's University
James Fraser, Queen's University
As nanophotonics becomes increasingly complex, diverse and precise methods of investigation are required at the atomic scale, leading to novel nanoscale structures and characterization techniques. In the new nanoPhotonics Research Centre, Queen’s University takes an interdisciplinary approach (across physics, chemistry, and engineering), to establish shared facilities that can make simultaneous measurements across different platforms, exploiting scanning probe microscopy, ultrafast light sources, and single-photon detection (visible and infrared). Progress on time-correlated single-photon counting modules and initial studies on single quantum dots will be discussed.
