摘要: The invention relates to a method of improving the performance of optical receivers within optical transceivers by compensating for crosstalk, both optical and electrical. Optical crosstalk may arise within the optical receiver from a variety of sources including directly from the optical emitter within, indirectly from the optical emitter via losses, and losses of other received wavelengths within the optical transceiver coupled to the optical receiver. Electrical crosstalk may arise for example between the electrical transmission lines of the optical transmitter and optical receiver. The method comprises providing a secondary optical receiver in predetermined location to the primary optical receiver, the optical receivers being electrically coupled such that the crosstalk induced photocurrent in the secondary optical receiver is subtracted from the photocurrent within the primary optical receiver. The method may be applicable to either monolithic and hybrid optical transceivers.
