Abstract
Optical telecommunication modules including transmitters and receivers and methods of using same. In some embodiments the transmitters include a chip having an array of lasers and a combiner for combining light from the lasers for transmission over an optical fiber. Preferably the lasers have widely spaced wavelengths. The chip may be semi-cooled in some embodiments. A dither signal may be provided to one laser for use by a receiver in tracking temperature of the laser for improved receiver performance. In some embodiments a plurality of EMLs are used instead of a greater number of plurality of DFBs for transmission.
