[edit] Expand to include optical devices?

Will the passive component definition still be correct if it is expanded to include certain optical devices? In particular, a beam splitter, as used on a passive optical network, acts on a signal without increasing its power and without requiring the use of an outside power source in order to operate. This sounds just like other passive optical devices, only it uses light rather than electricity. However, I do not know for certain whether or not passive components necessarily must be electrical. If you happen to have seen the term "passive component" used in conjunction with optical components, or if you are an expert in this area, please join the discussion!

diodes are considered an Active component under the WIKI Electronic Components. Diodes are typically made from semiconductors or tubes, tho early versions were made from other materials.Wamnet 22:20, 7 April 2007 (UTC)
