Dissertation Talk: Engineering Optical Antenna for Efficient Local Field Enhancement
Seminar: Departmental | December 14 | 1-2 p.m. | Cory Hall, 521 (Hogan Room)
Tae Joon Seok
Optical antennas have been widely used for variety of applications such as sensitive photodetection, efficient light emission, high resolution imaging, heat-assisted magnetic recording, and surface-enhanced Raman spectroscopy (SERS) since they can capture and focus propagating electromagnetic energy into sub-diffraction-limited area, and vice versa. However, widespread application of optical antennas has been limited due to lack of appropriate methods for uniform and large area fabrication of antennas as well as difficulty in achieving an efficient design with small mode volume (gap spacing < 10nm).
