SUMMARY:Summer Student Seminar
DESCRIPTION:Featuring Aaron Greenberg (Photonics)\nHosted by: Eric Boyers\n
	\nPart of the Graduate Student Council Events.\n\nAaron Greenberg (Photonic
	s)\nSingle-shot\, sub-picometer-resolution spectrometer using topologically
	 enhanced optical activity of OAM fiber modes\n\nLight with helical wavefro
	nts carry orbital angular momentum (OAM) that twist around depending on its
	 topological charge. These beams can also carry spin angular momentum (SAM)
	\, which just depends on whether it is right or left circularly polarized. 
	With the development of vortex fiber\, we can now stably propagate these ki
	nds of modes over long distances\, which have allowed these OAM beams to be
	come useful in STED microscopy\, communication\, laser machining\, etc. Her
	e I will introduce a new application of these OAM beams: high resolution sp
	ectroscopy. This is accomplished by leveraging the spin-orbit interaction (
	SOI) of light\, and by exploiting the inherent circular birefringence of vo
	rtex fiber modes yielding giant\, tailorable\, and wavelength-dependent opt
	ical activity.
