Abstract
The field of the invention is that of optoelectronic devices for receiving high bit rate digital optical signals for telecommunications applications, comprising an optical amplifier and a photoreceiver diode.Generally, the two optical amplification and optical-electrical conversion functions are integrated in a common component, resulting in lower production costs, smaller footprint and improved reliability.To optimize the conversion device as a whole, it is demonstrated that there must be an active area of small thickness in the amplifier part and greater thickness in the conversion part.The invention proposes to implement this function by means of a structure comprising a diluted multimode waveguide common to the two amplification and reception sections, the first active area and the second area being disposed so as to ensure a coupling by evanescent waves with said diluted multimode waveguide.
