A voltage controlled layer for a bi-directional device (106) is provided. A bi-directional device (106) having a working portion (110) and a surface (103) is operably coupled to substrate. An optically transparent layer (109) of elastic material is placed on the working portion (110) of the bi-directional device (106). A first and a second electrode (116, 117) are attached to the top and bottom surfaces (111, 112) of the optically transparent layer (109) to vary the thickness of the optically transparent layer (109) to accomodate the reception of transmission of light (130, 131) by the bi-directional device (106).
