ABSTRACT OF THE DISCLOSURE ALIGNMENT PROCESS OF AN ELECTRO-OPTICAL DEVICE The invention concerns the adjustment of electro-optical devices called "optical heads" that associate a semiconductor, laser diode or electroluminescent component and an optical component, such as an optical fiber. These devices must be aligned with a precision of from ?1 to ?10µ According to the process, the semiconductor component is integral with a centring part through the intermediary of a first bracket. The optical component, through the intermediary of a second bracket, is integral with a container in which is placed a hardening material. The centring part is plunged in the hardening material, with three degrees of mobility. The alignment is dynamic. When adjustment has been made, the hardening material is rapidly and rigidly fixed. Application to optoelectronics : optical fibers, telecommunica- tions.
