An optical interface device for a photonic integrated system includes a plug and a receptacle. The receptacle is operably arranged on a PIC that supports waveguides. The plug operably supports optical fibers. The receptacle and plug are configured to operably engage to establish optical communication between the optical fibers and the waveguides. A tab on the receptacle is configured to constrain longitudinal motion while allowing for lateral motion of the receptacle to adjust its position relative to the PIC to optimize alignment. The plug can include a spacer sized to fit within a recess defined by the tab to further facilitate alignment. The receptacle and plug can be engaged and disengaged in a manner similar to conventional electrical connectors.
