High Fidelity MMI-Based Multi-Spot Excitation for Optofluidic Multiplexing
09:00-09:15
2017-10-05 09:00 2017-10-05 09:15 America/Denver High Fidelity MMI-Based Multi-Spot Excitation for Optofluidic Multiplexing Producing high fidelity multi-spot patterns from a long ARROW-based multimode interference waveguide is important for optofluidic biosensors that rely on optical multiplexing. We have found that spot pattern fidelity is affected by input waveguide geometry and etching parameters. Hilton Santa Fe Historic Plaza Salon VII

Laser micro-ablated multi-point side-firing optical fiber for deep-tissue light delivery
09:15-09:30
2017-10-05 09:15 2017-10-05 09:30 America/Denver Laser micro-ablated multi-point side-firing optical fiber for deep-tissue light delivery A compact light delivery device capable of delivering light to multiple desired locations is essential for many biomedical applications. Here, we demonstrate the use of laser micro-ablation to create controllable conical-shaped cavities on optical fiber to enable a multi-point side-firing configuration using a single fiber.

Ensemble plasmonic coupling in disordered nanoparticle arrays and applications in ultra-sensitive biosensing and super-resolution histopathology Invited
09:30-10:00
2017-10-05 09:30 2017-10-05 10:00 America/Denver Ensemble plasmonic coupling in disordered nanoparticle arrays and applications in ultra-sensitive biosensing and super-resolution histopathology Plasmonic nanostructures permit light-excited surface plasmon resonance for applications in sensing, imaging, energy and catalysis. Ensemble plasmonic coupling (EPC) occurs when plasmonic NPs within a group interact. In this talk, I will discuss new results of far- and near-field EPC for biomolecular sensing and histopathology.
