| 摘要 |
An input signal supplied by a generator (30) is applied to a laser emitter diode (10) through a predistortion circuit in order to enhance the linearity of the response of the source. This circuit includes a linear pi-type attenuator stage consisting of resistors (12, 13, 14, 15 and 16), and a non-linear compensator element consisting of a Schottky diode (20) connected in parallel with this attenuator stage. The invention applies especially to the production of optical heads for optical-fibre telecommunication systems. <IMAGE> |
