About Us
Welcome
to the 3D Optical Systems group webpage at MIT. Our research is
in the area of information photonics, i.e. the combined use of
light and digital processing to acquire, process or transfer information
(i.e. sensing, computing, and communication.) Our particular goal
is to identify novel ways of utilizing the 3rd dimension to maximize
the information throughput of photonic systems. The three major
directions of our research in 3D information photonics are:
-
3D optics : we design and build lenses
with very unusual properties, e.g. the capability to extract
“tomographic” (3D) images and “hyperspectral”
images (i.e. color-specific with hundreds of color channels)
with high resolution, long working distance, small overall
system size (no multi-element lens trains!) and minimal scanning.
In addition, we research in the area of Digital Holography to develop a lens-less (3D) imaging system for underwater exploration.
-
micro-opto-mechanics
for integrated optics: we design and fabricated micromechanical
structures for use in guided wave systems for telecommunications
and sensing, for example tunable Bragg gratings, switchable
and tunable resonant wavelength filters, etc.
-
the
nanostructured origami™
3D fabrication and assembly method will eventually allow us
to manufacture 3D nanosystems with exclusive use of 2D litho
tools. Thus, we can still exploit the 3rd dimension without
being limited by the difficulties of semiconductor infrastructure
to deal with volumes.
