An optical device for processing a digital optical signal in parallel and in free space, the said device comprising: a) means of input in guided propagation of a digital optical signal comprising at least one temporal series of n bits; b) means capable of converting the said digital optical signal to a beam of n digital optical signals in guided propagation, each comprising at least one temporal series of n bits; c) means capable of converting the said beam of n digital optical signals in guided propagation, each comprising the said at least one temporal series of n bits, to a beam of n digital optical signals in free space; d) means capable of selecting, in parallel and in free space, a bit preselected from the said at least one temporal series of n bits of each of the said n digital optical signals, so as to transform the said at least one temporal series of n bits into a spatial figure of the said n bits which carries the same information as that previously contained in the said at least one temporal series, the said device further comprising e) optical means capable of modifying, in parallel and in free space, at least one bit of the said spatial figure of the said n bits, the said means being selected by a group comprising means capable of eliminating at least one bit, means capable of inserting at least one bit and means capable of modifying the form of at least one bit, and f) means of output of a processed digital optical signal, comprising at least one series of n bits.
L'invention est un dispositif optique utilisé pour traiter les signaux lumineux numériques en propagation guidée ou en propagation dans l'espace libre qui comprend : a) un dispositif servant à introduire dans un guide de propagation un signal lumineux numérique comprenant au moins une suite temporelle de n bits; b) un dispositif pouvant convertir ce signal lumineux numérique en un faisceau de n signaux lumineux numériques en propagation guidée, chacun de ces signaux comprenant au moins une suite temporelle de n bits; c) un dispositif pouvant convertir ce faisceau de n signaux lumineux numériques en propagation guidée comprenant chacun ladite ou lesdites suites temporelles de n bits en un faisceau de n signaux lumineux numériques se propageant dans l'espace libre; d) un dispositif pouvant sélectionner, en modes de propagation guidée et de propagation dans l'espace libre, un bit présélectionné parmi ladite ou lesdites suites temporelles de n bits de chacun de ces n signaux lumineux numériques de façon à transformer ladite ou lesdites suites temporelles de n bits en une figure spatiale de ces n bits qui contient la même information que celle contenue précédemment dans ladite ou lesdites suites temporelles, ce dispositif optique comprenant de plus e) un élément optique pouvant modifier, en mode de propagation guidée ou de propagation dans l'espace libre, un bit au moins de ladite figure spatiale parmi les n bits cités, cet élément étant sélectionné par un groupe comportant un élément capable d'éliminer un bit au moins, un élément capable d'introduire un bit au moins et un élément capable de modifier la forme d'un bit au moins, et f) un élément servant à transmettre un signal lumineux numérique comportant au moins une suite de n bits.
