Abstract
An optical data communication device includes a plurality of emitters. The plurality of emitters are configured to emit respective laser beams that are associated with a same spectral range and that are to couple into an input end of a multi-mode optical fiber. A size of an oxide aperture of each emitter, of the plurality of emitters, is less than or equal to 3.5 micrometers. Each emitter is a single-mode emitter or a reduced-mode emitter. A pitch between adjacent emitters is less than or equal to 30 micrometers. The plurality of emitters are disposed in a configuration pattern, wherein a central region of the configuration pattern does not include any emitter of the plurality of emitters.
