   Presenter: Rebecca Richards-Kortum, Rice University, United States

    Presentation Details

   Plenary

   Cancer is the first and second leading cause of premature death in 134 of 183 countries and it is estimated that global incidence of cancer will increase by 50% from 2018 to 2040. The number of cases is projected to double in countries with low Human Development Index; these countries have the least resources and infrastructure to adequately care for cancer patients. This talk will describe development and deployment of affordable, accurate technologies that integrate imaging and biomarkers for use in low-resource settings. Examples will include systems for early detection of precancerous leisons and for histopathologic cancer diagnosis.Authors: Rebecca Richards-Kortum, Rice University

   Plenary

   The advancement of sensing, interconnects and computing in the last one hundred years is mainly from the R&D works on electrons and photons, which carry drastically different characteristics defining different technology roadmaps. Due to the saturation of the Moore’s law, the advantages of photon-based devices provide solutions with the unprecedented performance. In this talk, we will present the integrated photonic devices covering near and mid-IR wavelengths for spectroscopy, biosensing and SERS. Mid-IR Lidar Chip centered at 4.6 micron will also presented.

Here, we demonstrate an asymmetric Bragg grating mode coupler in thin-film lithium niobate with 1 dB insertion loss.Authors: Lars Emil Gutt, Danmarks Tekniske Universitet / Thach Nguyen, RMIT / Peter Girouard, Danmarks Tekniske Universitet / Guanghui Ren, RMIT / Leif Oxenløwe, Danmarks Tekniske Universitet / Bill Corcoran, Monash University / Arnan Mitchell, RMIT / Pengyu Guan, Beijing Institute of Technology

   Multiband electro-optic modulator employing a lithium niobate racetrack resonator integrated with two pulley couplers

   Presenter: HYEON HWANG, KAIST, Korea (the Republic of)

    Presentation Details

   We present a multiband electro-optic modulator based on a lithium niobate racetrack micro-resonator. Integration with two pulley couplers allows high-extinction modulation over multiple spectral bands of 775, 980, and 1550 nm in a single device.Authors: HYEON HWANG, KAIST / Mohamad Reza Nurrahman, KAIST / Hyungjun Heo, Korea Institute of Science and Technology (KIST) / Kiyoung Ko, KAIST / Kiwon Moon, Electronics and Telecommunication Research Institute (ETRI) / Jung Ju, Electronics and Telecommunication Research Institute (ETRI) / Sang-Wook Han, Korea Institute of Science and Technology (KIST) / Hojoong Jung, Korea Institute of Science and Technology (KIST) / Hansuek Lee, KAIST / Min-Kyo Seo, KAIST

   High-Resolution Arrayed-Waveguide-Grating-Assisted Passive Integrated Optical Phased Array for 2-D Beam Steering

   Presenter: Yuan Liu, University of California Santa Barbara, United States

    Presentation Details

   We demonstrate a 64-channel arrayed-waveguide-grating-assisted silicon-nitrite integrated optical phase array (OPA) for 2-D beam steering. A field of view of 5°×25° with 0.3° vertical resolution are achieved over a wavelength range of 100 nm through a single input. Higher vertical resolution can be attained by utilizing all the inputs of the OPA.Authors: Yuan Liu, University of California Santa Barbara / Chongxin Zhang, University of California Santa Barbara / Daniel DeSantis, Massachusetts Institute of Technology / Diya Hu, University of California Santa Barbara / Thomas Meissner, University of California Santa Barbara / Andres Garcia Coleto, Massachusetts Institute of Technology / Benjamin Mazur, Massachusetts Institute of Technology / Jelena Notaros, Massachusetts Institute of Technology / Jonathan Klamkin, University of California Santa Barbara
