    Wayfair: Establishing an Economic Nexus Standard for the 21st Century
    (2020-04-20) Hebert, Daniel J.;
    In this article, Hebert discusses state and local tax jurisprudence before South Dakota v. Wayfair, the effects of Wayfair on economic actors and states, and recommendations regarding post-Wayfair state legislation.

    Open Scholarship on a Shoestring
    (2018-06) Hewitt, Rebecca; Parker, Jennifer; Pritting, Shannon;
    Grant funding has been central to SUNY Polytechnic’s leadership in the open access (OA) campaign on campus. Partnering with SUNY, regional, and campus associations, our library has won thousands of dollars to support educational access and affordability initiatives. Projects are selected strategically to align with campus OA priorities and faculty and student needs. Contributions to NY Heritage, SUNY Poly’s institutional repository, course reserves, professional exam prep, and adoption of a purchase on demand model are examples of projects that have been completed successfully, and more are underway.

    Using Small Grants to Make the Library a Driver of College & Career Access and Affordability
    (2018-06) Hewitt, Rebecca; Parker, Jennifer;
    Since our limited collection budget could not support the purchase of textbooks on an annual basis, we applied for a small grant from our institute’s Auxiliary Services Corporation, and were awarded $5000 for this purpose in the summer of 2017. Altogether we purchased 46 textbooks during the 2017-18 academic year. The initiative proved so popular that the Student Government Utica awarded us $2000 to continue the next year, and we also were given another $2000 from Auxiliary Services. Remarkably, though, it wasn’t the texts that we purchased that were the most heavily used. Ebooks already in the library collection, made easily discoverable through our extensive textbook marketing campaign, were used most often.

    Broadband 2-μm emission on silicon chips: Monolithically integrated Holmium lasers
    (Optical Society of America, 2018) Li, Nanxi; Magden, Emir Salih; Su, Zhan; Singh, Neetesh; Ruocco, Alfonso; Xin, Ming; Byrd, Matthew; Callahan, Patrick T.; Bradley, Jonathan D.; Baiocco, Christopher; Vermeulen, Diedrik; Watts, Michael R.;
    Laser sources in the mid-infrared are of great interest due to their wide applications in detection, sensing, communication and medicine. Silicon photonics is a promising technology which enables these laser devices to be fabricated in a standard CMOS foundry, with the advantages of reliability, compactness, low cost and large-scale production. In this paper, we demonstrate a holmium-doped distributed feedback laser monolithically integrated on a silicon photonics platform. The Al2O3:Ho3+ glass is used as gain medium, which provides broadband emission around 2 μm. By varying the distributed feedback grating period and Al2O3:Ho3+ gain layer thickness, we show single mode laser emission at wavelengths ranging from 2.02 to 2.10 μm. Using a 1950 nm pump, we measure a maximum output power of 15 mW, a slope efficiency of 2.3% and a side-mode suppression ratio in excess of 50 dB. The introduction of a scalable monolithic light source emitting at > 2 μm is a significant step for silicon photonic microsystems operating in this highly promising wavelength region.

    Octave-spanning coherent supercontinuum generation in silicon on insulator from 1.06μm to beyond 2.4μm
    (Changchun Institute of Optics, Fine Mechanics and Physics, 2018) Singh, Neetesh; Xin, Ming; Vermeulen, Diedrik; Shtyrkova, Katia; Li, Nanxi; Callahan, Patrick T.; Magden, Emir Salih; Ruocco, Alfonso; Fahrenkopf, Nicholas; Baiocco, Christopher; Kuo, Bill P-P; Radic, Stojan; Ippen, Erich; Kärtner, Franz X.; Watts, Michael R.;
    Efficient complementary metal-oxide semiconductor-based nonlinear optical devices in the near-infrared are in strong demand. Due to two-photon absorption in silicon, however, much nonlinear research is shifting towards unconventional photonics platforms. In this work, we demonstrate the generation of an octave-spanning coherent supercontinuum in a silicon waveguide covering the spectral region from the near- to shortwave-infrared. With input pulses of 18 pJ in energy, the generated signal spans the wavelength range from the edge of the silicon transmission window, approximately 1.06 to beyond 2.4 μm, with a − 20 dB bandwidth covering 1.124–2.4 μm. An octave-spanning supercontinuum was also observed at the energy levels as low as 4 pJ (−35 dB bandwidth). We also measured the coherence over an octave, obtaining gð1Þ 12 l ð Þ >90%, in good agreement with the simulations. In addition, we demonstrate optimization of the third-order dispersion of the waveguide to strengthen the dispersive wave and discuss the advantage of having a soliton at the long wavelength edge of an octave-spanning signal for nonlinear applications. This research paves the way for applications, such as chip-scale precision spectroscopy, optical coherence tomography, optical frequency metrology, frequency synthesis and wide-band wavelength division multiplexing in the telecom window.
