Plasmon Resonators for Quantum Computing
Abstract
The purpose of this project was to develop high-performance plasmon-based nano-optics that can be used to coherently couple single optical emitters to each other or to incoming photons for quantum information applications. The constraint was to fabricate these structures with nanolithographic process such as e-beam lithography, so that precise reproducibility and placement accuracy can be achieved. Initially, the emphasis was on duplicating the performance of fractal-like structures grown by self-assembly. However, difficulties in achieving the necessary sub-5-nm resolution led to the exploration of two other structures. One of these was an infrared LC resonator with an adjustable coupling to the IR field. The motivation for this was to allow optimization of the structure so that an optical version it could be placed on a high Q evanescent optical cavity, without degrading cavity performance. A microwave-frequency version of the structure was first fabricated and tested with a custom near-field probe to validate the simulations. The second structures to be studied were optical wires with normal incidence input/output light coupling structures. Wires with dimensions as low as 50 x 50 nm with lengths up to 15 microns were fabricated. The transmission losses at 632 nm compared favorably to self-assembled metal wires.
