Proposed integrated in-line array of semiconductor lasers intended to provide high reliability and/or long operating lifetime. Multiple integrated collinear semiconductor lasers share common optical waveguide but individually electrically excited. When one device fails, another switched on. Important advantage in systems in which both reliability of diode lasers and alignment of those lasers with other optical components critical.
