Abstract

An optical communication system including an integrated circuit chip, an electro-optical chip operatively integrated on the integrated circuit chip, an adjustable optical chip which includes at least one optical element disposed between the electro-optical chip and one of a source or recipient of at least one optical signal, at least one micromachine operatively coupled to the at least one optical element to selectively manipulate the at least one optical element; an optical signal sensor disposed relative to the at least one optical signal to sense an optical signal condition data, and to transmit said optical signal condition data to the integrated circuit chip, a feedback circuit between the integrated circuit chip and the at least one micromachine, the integrated circuit chip configured to receive the optical signal condition data, convert it to a corresponding feedback signal, and to transmit the feedback signal through the feedback circuit to the micromachine, thereby causing the micromachine to selectively manipulate the at least one optical element to alter the optical signal.
