Optical circuits based on polariton neurons in semiconductor microcavities
Physical Review Letters, 2008•APS
By exploiting the polarization multistability of polaritons, we show that polarized signals can
be conducted in the plane of a semiconductor microcavity along controlled channels or
“neurons.” Furthermore, because of the interaction of polaritons with opposite spins it is
possible to realize binary logic gates operating on the polarization degree of freedom.
Multiple gates can be integrated together to form an optical circuit contained in a single
semiconductor microcavity.
