    OSC Students and Faculty were recognized at SPIE for multiple honors. Congratulations to the awardees!

    Best Student Paper

    Brandon Hellman, Joshua Rodriguez, Chuan Luo, HeeJoo Choi, and Yuzuru Takashima received the Best Student Paper award for their paper on "Angular and spatial light modulation by single digital micromirror device for beam and pattern steering."

    Paper Abstract:
    Angular and spatial light modulation by single digital micromirror device for beam and pattern steering Paper 11294-11 The “Angular Spatial Light Modulator” (ASLM) uses a binary patterned programmable blazed grating to increase the étendue and number of output pixels of a DMD by merging geometric and diffractive optical capabilities of the DMD. We demonstrate a series of capabilities of the ASLM for beam and pattern steering. In particular, a single-chip beam steering lidar, an extended FOV display, a light-field projector, and a multi-view display which can be implemented into AR/VR/3D systems. We also present our metrology results of wavefront distortion and diffraction efficiency of the DMD while micromirrors are transitioning between on and off states. # Emerging Digital Micromirror Device Based Systems and Applications XII Tuesday - Wednesday 4 - 5 February 2020 SPIE Photonics West.

    Best Student Talk

    Adley Gin, mentored by Judy Su, was awarded the Best Student Talk for his research "Label-free ultrasensitive detection of Amyloid-β using microtoroid resonators with lipid surface functionalization." Gin said of his research, "We utilized silica microtoroid optical resonators with lipid membrane surface functionalization as a biosensor for detecting Amyloid-β, a biomarker for Alzheimer's disease. The goal is to exploit the high sensitivity of these optical resonators and create a platform for a blood-based assay for early detection of Alzheimer's disease."

    Prizmatix Young Investigator Award

    Cheng Li, mentored by Judy Su, received the Prizmatix Young Investigator Award for his research, "Particle shape analysis using whispering gallery mode polarization sensing." Li said of his research, "We built a dual-FLOWER (frequency locked optical whispering evanescent resonator) system to achieve shape reconstruction of gold nanoparticles. The system simultaneously tracks two whispering gallery modes with different polarizations to derive the dimension for the corresponding axis. We will further demonstrate this method on bioparticle in the nano-scale."
