Electrooptic probe based on an organic microcavity
Résumé
We present the concept of an electrooptic (EO) probe based on a thin organic layer of DR1-PMMA embedded in a high finesse Fabry-Pe/spl acute/rot cavity with optimal orientation of the DR1 molecules, parallel to the faces of the microcavity. This optimal orientation is obtained through a lateral poling method and an r/sub 33/ value of 2.5 pm/V is reached for a 16-/spl mu/m-thick DR1-PMMA layer. This EO probe shows a high sensitivity of 2 V/spl middot/cm/sup -1//spl middot/Hz/sup -1/2/.
