An optocasule unit for an optohybrid assembly (10), said capsule unit comprising a lower casing part (36) and a compatible upper cover part (54) which together form, at one end (50) thereof, an integral receptacle section for obtaining an optomechani-cal interface and receiving and detachably holding therein an optical connector with at least one external optical fiber. A central section (38) of the lower casing part (36) has a cavity (42) for receiving, in a form-closed manner, a ferrule (12) of the opto-hybrid assembly (10). The lower casing part (36) has, at a second end thereof, a base plate (44) for supporting a substrate (20) having at least one optochip (26, 28) and a proximal end of at least one primary optical fiber (22, 24) mounted thereon. The cover part (54) also has a section (58) covering the substrate (20) and at least a por-tion of the base plate (44) of the lower part. The invention is also addressed to the lower casing part (36) of the optocapsule unit for enclosing an optohybrid assembly (10) therein, and to an optoelectronic module (62) comprising the capsule unit with an optohybrid assembly enclosed therein.

La présente invention concerne une capsule optique destinée à un ensemble optique hybride (10). Cette capsule est constituée d'un plancher (36) et de son capot (54) qui réunis, forment sur l'une des extrémités du plancher, un élément mâle monobloc accueillant une interface opto-mécanique pouvant retenir de façon détachable un connecteur optique desservant au moins une fibre optique externe. La zone centrale (38) du plancher (36) comporte une cavité (42) servant à accueillir, à l'état fermé, une virole de l'ensemble optique hybride (10). A son autre extrémité, le plancher comporte une palette support (44) accueillant un substrat (20) porteur d'au moins un microcircuit optique (26, 28) et l'extrémité proximale d'au moins une fibre optique primaire (22, 24). Le capot (54) comporte également une zone (58) recouvrant le substrat et au moins une partie de la palette support (44) du plancher. L'invention concerne également, d'une part un plancher de boîtier (36) de capsule optique destinée à renfermer un ensemble optique hybride, et d'autre part module optronique (62) équipé de la capsule renfermant un ensemble optique hybride.
