Abstract
A surface emitting laser is coupled to an external modulator. The laser and the modulator aligned by photolithographically defined features. In a preferred embodiment, the electromagnetic output of the laser is reflected at a right angle from a mirror mounted on a substrate. The reflected output enters a modulator mounted on the same substrate as the mirror. A circuit coupled to the modulator controls the modulation undergone by the electromagnetic output. The modulated output is coupled to an optical fiber for transmission.
