Abstract
A multi-wavelength laser array has a group of multiple lasers, each of the lasers in the group being constructed to emit at a specified wavelength within a range, the specified wavelength of one laser being different from the specified wavelength of the other lasers in the group. The lasers in the group are individually selectable so that, when emission at a particular wavelength is called for, a laser capable of providing the particular wavelength will be selected.
