Patent ID: 7282689

Claim:
An optical fibre receiver for an opto-electronic integrated circuit (OEIC), comprising at least one photo-receiver ( 11 ) and at least one transimpedance amplifier, wherein (i) the photo-receiver ( 11 ) is divided into several partial photo-diodes (D 1 , D 2 , D 3 , D 4 ) in order to consist of a number of individual photo-diodes, wherein the size of the partial photo-diodes is adapted to that of a spot of light projected onto the photo-receiver ( 11 ); (ii) each partial photo-diode (D 1 , D 2 , D 3 , D 4 ) is connected to an own transimpedance amplifier ( 20 , 21 , 22 , 23 ), and the electrical output signals of the transimpedanee amplifiers ( 20 , 21 , 22 , 23 ) are combined electrically by a summing amplifier ( 30 ); and (iii) wherein at least the photo-receiver ( 11 ), the transimpedance amplifiers and the summing amplifier ( 30 ) are monolithic integrated onto a chip together with other circuit components.
