Avec des avantages significatifs en termes de vitesse, de bande passante et d'�conomie d'�nergie, l'informatique optique est apparue comme un substitut possible � l'informatique �lectrique conventionnelle. Les concepts de manipulation de la lumi�re, les composants utilis�s dans les syst�mes informatiques optiques et plusieurs mod�les de calcul sont tous abord�s dans ce chapitre qui explore les fondements de l'informatique optique. L'optique est utilis�e dans l'informatique depuis longtemps, mais l'accent a �t� mis et continue d'�tre mis sur la liaison des composants informatiques, pour les communications, ou plus fondamentalement dans les syst�mes qui incluent une fonction ou une caract�ristique optique (reconnaissance optique des formes, etc.). Bien que les ordinateurs num�riques optiques en soient encore � leurs balbutiements, le pr�sent document examine un certain nombre de d�veloppements ant�rieurs qui pourraient un jour d�boucher sur de v�ritables ordinateurs optiques, notamment les portes logiques optiques, les commutateurs optiques, les r�seaux neuronaux et les modulateurs spatiaux de lumi�re. Des dispositifs et syst�mes photoniques plus complexes peuvent �tre simul�s et construits avec pr�cision � l'aide d'ordinateurs haute performance disponibles sur le march�.
