Project Title:3D Nanophotonics in Artificially Structured Chalcogenide
Materials
Project Rationale and Description:
Currently, the realization of three-dimensional (3D) confinement of photons
in artificially structured electromagnetic materials or photonic crystal
(PhC) has proven to be very challenging. Some approaches based on an
inverse-opal PhC, a woodpile crystal, and the 2D–3D hybrid PhC systems
combined with lithography are developed. To achieve high design flexibility
and less fabrication difficulty, we have reported inverse rod-connected
diamond (RCD) structured chalcogenides with 3D direct laser writing
(DLW) using two-photon polymerization, followed by chemical vapor
deposition (CVD).
In this project, the student will study the inverse design of diamond lattice
structures (e.g. inverse RCD and inverse woodpile crystals) only based
on removing or adding materials to create low-index or high-index cavities
[1,2]. Similarly, the waveguide networks are formed by either a single rod or
a series of sphere fragments where light is confined and guided by wave
interference rather than total internal reflection; each layer is linked by
oblique waveguides.
For the fabrication and characterisation of these structures, we will
collaborate with partner universities in Bristol and Southampton to access
their facilities including DLW, CVD, and Fourier image spectroscopy (FIS)
systems. The project will develop the model (using electromagnetic simulation
software, CST) which can be used to provide data to guide device design, when
compared with angle-resolved light scattering characterisation using FIS and
enabled an estimation of device quality at each fabrication step.
Such a high-Q cavity with ultra-small mode volume could be used
to demonstrate strong coupling at elevated temperatures, while coupled
cavities of this type could form broad bandwidth, lossless, wavelength scale
optical circuits in a fully 3D photonic microchip. The 3D microchips could
allow the development of novel nanophotonic devices including ultrasensitive
gas sensors, artificial nanostructured composite materials for energy
harvesting and all optical artificial neural networks with 3D nanocavities
and waveguide networks.
