He became known especially for his pioneering works in nano-optics, near field optics (NFO), and plasmonics.Pohl studied at the University of Stuttgart and the Technische Universität München (TUM) where he did his doctorate with Wolfgang Kaiser.
1999 Dieter Pohl suggested antennas as ideal sources or probes of localized optical near-fields.
The intensity caused higher order nonlinear light emission, an interesting fact in view of the tiny near-field spot.
In 1992, Dieter Pohl and Daniel Courjon organized a workshop on near-field optics (NFO)[15] that was to become the origin of bi-annual international NFO-x conferences (2018: x = 15), a platform for nano-, near-field-, nonlinear optics, plasmonics, metamaterials, quantum information, biosensing and ultrafast dynamics.
He acted as reviewer for the Swiss National Science Foundation (SNF) and the German DFG.
