ABSTRACT:
An optical switch having liquid or vapor bubbles at switching sites operates with a fluid pressure less than the vapor pressure of the liquid. This negative pressure differential reduces the energy required to maintain a bubble at a switching site. Local heating provides the energy to create or maintain a bubble and activate a switching site, and turning off the heating collapses the bubble and deactivates the switching site.
