Optimization of a plasmonic-enhanced photodetector design
Abstract/Contents
- Abstract
- This thesis covers the design and investigation of a plasmonic-grating enhanced photodetector structure that consists of a series of concentric gratings around a bull's eye that is split to form a metal-semiconductor-metal photodetector. Finite-difference-time-domain (FDTD) studies were carried out in order to study and simulate the different parameters of the photodetector design. A fabrication process was suggested that makes use of two lithographic mask layers in order to fabricate the basic metal-semiconductor-metal photodetector structure in InGaN where the bull's eye grating is to be patterned on. Initial fabrication work was done on making the concentric gratings and bull's eye structures using focused-ion-beam milling on a metal layer as a test. In addition, these plasmonic-grating enhanced photodetector structures were shown to be wavelength selective, and such a characteristic can be used to design multi-spectrum detectors for bio-sensing. A design for a multi-spectrum biosensor using microfluidic channels and multiple plasmonic-grating enhanced photodetectors is also described in the thesis.
