Polaritonic structure imaging

October 31, 2006

12:00 noon - 1:00 p.m.
Grier Room 34-401




Abstract:

Phonon-polaritons, admixtures of electromagnetic and polar optic 
phonon modes, allow the generation and detection of THz frequency 
electromagnetic fields within electro-optic structures patterned into 
common ferroelectric crystals such as LiNbO3 and LiTaO-3. The 
mechanical component of phonon-polaritons, allows direct imaging of 
these polaritons, and thus the EM field, throughout a photonic 
structure.

The behavior of various simple photonic structures such as slab 
waveguides, coupled waveguides, and resonant cavities will be 
presented.  Additionally, the response of polaritonic bandgap 
structures, photonic crystals in materials that have a material 
(polaritonic) resonance near to the imposed photonic resonance, will 
be presented..
