PIC device concepts are difficult to grasp, and explanations typically require the solution of Maxwell’s equations. Laboratory experiments which demonstrate the testing of these devices can offer some intuition into device functionality. However, photonics device test on an unpackaged die requires a complicated equipment set-up because devices, both passive (all optical) and active (opto-electronic), need precise (~nm) optical alignment. Online asynchronous courses, Integrated Photonics Test: Passive Devices (IPT:Passive) and Integrated Photonics Test: Active Devices (IPT:Active), that teach hands-on laboratory testing of volume-manufactured photonic integrated circuit (PIC) devices are created as a multi-instructor collaborative approach with lectures and laboratory videos and exercises.
Recent integrated optical phased array architectures, results, and applications will be reviewed. Beam-steering optical phased arrays monolithically integrated with on-chip rare-earth-doped lasers and heterogeneously integrated with CMOS driving electronics will be shown. Passive integrated optical phased arrays that focus radiated light to tightly-confined spots in the near field and that generate quasi-Bessel beams will be discussed. Finally, integrated-phased-array-based visible-light holographic displays will be proposed as a scalable solution towards the next generation of augmented-reality head-mounted displays; passive near-eye holographic displays, visible-light liquid-crystal modulators, and liquid-crystal-based visible-light phased arrays will be presented.
