英文摘要	A semiconductor laser capable of emitting in any one of standard communication wavelengths is of great practical value. To this end, a single semiconductor chip is fabricated on which many different distributed feedback (DFB) lasers are integrated. The device parameters of the different DFB lasers are varied such that each laser emits at a different wavelength. In addition a micro-mechanical optical element is packaged with the laser array, such that the position of the optical element controls which laser stripe is coupled to the output fiber. The micro-mechanical element or switch in various embodiments is a sliding waveguide, a movable lens, or a mirror that tilts. By selecting the particular DFB laser, controlling the temperature to fine tune the wavelength, and adjusting the position of the micro-mechanical optical element, the output wavelength is set to one of many communication wavelengths.
