    • An active photonic semiconductor device, such as a laser, optical amplifier or LED, is monolithically integrated with a photodetector. The device includes an optically active region formed on a substrate including a first electrical contact for initiating emission of photons within the optically active region; an optical confinement structure generally defining a principal optical path through the device and through said optically active region; and a photodetector structure formed on the substrate including a second electrical contact displaced from and substantially electrically insulated from the first contact, overlying a part of the principal optical path, for receiving carriers generated by said emitted photons. The photodetector is preferably positioned to cover an intermixed / non-intermixed region close to a facet of the device and also close to the active region of the device. The photodetector is weakly coupled to the optical confinement structure such that a very small proportion of the optical radiation can be monitored without deleteriously affecting the performance of the device.

    • Diode type laser devices (diode lasers) with nonabsorbing windows that are obtained in low confinement asymmetric structures, asymmetric structures that consist of a waveguide and an active region, the active region being situated asymmetrically relative to the waveguide, at an extremity of the waveguide central layer, outside, at the margin or inside the waveguide central layer. The nonabsorbing mirrors are obtained by the partial etching of the diode lasers layered structures, by this etching the active region being removed but in a large extent the layered structure remaining unaffected, and by the regrowth of a material with an adequate crystalline structure and nonabsorbing for the radiation emitted by the laser. By etching - regrowth processes the optical properties of the waveguide are reconstructed in a large extent, so that the radiation propagates to the mirror into a waveguide similar with the waveguide of the rest of the laser.
