Chirality of the molecules is a necessary and sufficient condition for optical activity.
But there are exceptions : Chiral amines (reason - umbrella inversion results in a racemic mixture)

See : http://en.wikipedia.org/wiki/Optical_rotation   and   http://en.wikipedia.org/wiki/Chirality_%28chemistry%29

Presence of chiral center is not a necessity. Ex : Optically active allenes, biphenyls
