Cascaded-Mode Optics

Project Details


Photonics constitutes an essential backbone in modern applications, such as communication technology
and lithography. The manipulation of light is also crucial in several fundamental research areas, ranging
from experiments in quantum computing to the detection of gravitational waves. Recent developments in
nanotechnology allow for the fabrication of structures that manipulate light in extraordinary ways. In the
last decade, it has become possible to efficiently generate structured light. Structured light has the
potential to revolutionize both industrial applications and fundamental research. However, currently,
optical design does not fully exploit nanotechnology’s possibilities to generate and manipulate structured
light. Indeed, our current techniques in optical design calculate the properties of a structure that converts
an incident beam into another beam. This input-output perspective limits the light that can be generated.
In this project, I will develop a new paradigm in optical design based on cascaded-mode conversion. In
this approach, light bounces between communicating components: the same component interacts with
the light several times, each time exhibiting a different function. The implications of cascaded- mode
optics on optical design potentially permeate all areas of photonics. In this project, we will realize
cascaded-mode structured fields in complex devices, with applications in particle trapping and cavity
mode engineering.
