OPTICAL ALIGNMENT SYSTEMS AND METHODS USING SILICON DIODES

Abstract: an integrated photonics chip comprising: a plurality of optical channels extending a length of the integrated photonics chip; at least one variable optical attenuator (voa) being optically connected to one of the plurality of optical channels, the at least one voa comprising a silicon diode; at least one modulator being optically connected to another of the plurality of optical channels, the at least one modulator comprising a silicon diode; wherein the silicon diodes of the at least one voa and the at least one modulator are adapted to receive biasing voltages; and wherein an application of the biasing voltages causes the silicon diodes of the at least one voa and the at least one modulator to be reverse-biased, such that the at least one voa and the at least one modulator are each adapted to detect a photocurrent of an optical signal being propagated along the plurality of optical channels.
