    Additive diffractive optical elements fabrication by PECVP deposition of SiO2 and lift-off process

    (SPIE-Intl Soc Optical Eng, 2023-08-07) Amata, Hadi; Fu, Qiang; Heidrich, Wolfgang; Visual Computing Center (VCC); Computer, Electrical and Mathematical Science and Engineering (CEMSE) Division; Computer Science Program

    Diffractive optical elements (DOEs) gradually start replacing traditional refractive optics in many applications. The growing interest in DOEs is mainly because of their flexibility in light manipulation with a small form factor and their ability to combine simultaneously optical and computational functions into a single part by applying the software-hardware co-design approach. Two main methods are widely used to fabricate DOEs. The first method is the etched-based method that combines photolithography and reactive-ion etching (RIE). The second method is additive fabrication, which combines metal deposition and nanoimprinting (NIL). Both methods have many drawbacks. The RIE methods suffer from issues like lags in the etched depth when the feature sizes differ in the same pattern (RIE lags), high surface roughness, and aspect ratio-dependent etching rate. The second method could produce high-resolution micro-optics. However, the technique could suffer from poor adhesion of the patterns with the substrate and poor uniformity across large areas. Here we propose a new way to fabricate multi-level DOEs by directly growing an optically transparent material on a glass substrate. The method combines the deposition of Silicon dioxide (SiO2) by Plasma-enhanced chemical vapor deposition technique (PECVD) and bi-layer lift-off. We provide evidence of the effectiveness of the fabrication method by comparing a 16-level Fresnel lens fabricated by the RIE method with another lens fabricated by the proposed method. The characterization results show that with the proposed method, the surface roughness is lower, and the depth is uniform. Furthermore, the optical test shows a reduced haze effect.

    Exploring the Need for Intellectual Property Information Literacy for Business and STEM Disciplines

    (Springer Nature, 2018-01-19) Tyhurst, Janis; Collections & Information Services; University Library

    A major component of any information literacy training program incorporates training on copyright and fair use. While in the library literature, librarians have provided excellent training on understanding copyright and appropriate use, they have not focused on providing training on other forms of intellectual property (IP), particularly patents. As IP in the form of patents is becoming exponentially more important in the research-to-commercialization process, more work on information literacy training about patents is needed. This paper provides definitions of IP literacy, places the value of IP literacy in a larger context, looks at target audiences, proposes a framework for IP literacy and provides suggestions about the role that librarians can play in developing IP literacies beyond copyright.

    KAUST Open Access policy

    (2017-03-07) Baessa, Mohamed A.; University Library

    The transition to open access (OA) is being driven by funders, libraries, researchers and publishers around the world, and is having an impact on us all. It is inevitable that different countries, organisations and disciplines are moving at different rates towards an OA model, and it is this that we will focus on in this session. Drawing on experiences from across Europe and the Middle East we will provide perspectives from both a global publisher and institutions based in the region. Taylor & Francis take a flexible, evidence-based approach to open access, providing a choice of publication routes for our authors, and a choice of agreements for our library customers. Carolyn will outline some of the open access developments, opportunities and challenges at Taylor & Francis. The library plays a critical role in facilitating open access for their researchers, from managing a repository to providing support and information on the OA publication process to their authors. Janis Tyhurst and Dr Imad Bachir will each give an overview of how this is being managed by their institution. There will be an opportunity for questions and discussion with the panel.

    Design and Implementation of a Campus-Wide Online Plagiarism Tutorial: Role played by the Library in an emerging research institution in Saudi Arabia

    (2017-06-20) Han, Lee Yen; University Library

    Academic dishonesty and plagiarism are serious issues in institutes of higher education especially in this Internet age with academic literature and information readily available on the web. Some research studies point to the students’ lack of understanding of the concept of plagiarism and how to cite sources as reasons why they plagiarize (Volkov, Volkov, & Tedford, 2011). Academic librarians have an important role to play in providing instruction in the ethical use of information and helping students develop abilities to attribute and cite sources in their academic writing (Mages & Garson, 2010; Maxymuk, 2006).

    Recognizing this important role played by librarians, the University Library at King Abdullah University of Science and Technology (KAUST) started offering face-to-face workshops on the topic in the spring of 2015. While the workshops were positively received by the participants, informal feedback from students points to a need for an online course which would provide asynchronous just-in-time training for students. In this way, students who are not able to attend the face-to-face workshops would be able to access the tutorial in their own time and at their own pace.

    This paper reports on the process the University Library took to create and embed an online plagiarism tutorial in Blackboard, the Learning Management System (LMS) used by the university. Drawing on and expanding on materials covered in the face-to-face workshop, the online tutorial included original multimedia material, and a summative evaluation quiz. Improvements were made based on feedback gathered from students, library staff, and other university departments, such as the Office of Writing Services, Graduate Affairs, and ESP Instructors from the Writing Center. The online tutorial was initially planned as an optional course for students, but with the support of Academic Affairs and Graduate Affairs, it has been mandated as a compulsory course for all new in-coming students.
