Abstract
This invention combines a coherent multi-stripe laser array with a multi-stripe optical modulator. Light from different stripes of the multi-stripe laser are coupled to different stripes of the optical modulator. For example, the laser could comprise a first laser stripe, a second laser stripe, a third laser stripe and a fourth laser stripe. The modulator could comprise a first modulator stripe, a second modulator stripe, a third modulator stripe and a fourth modulator stripe. The light exiting from the first laser stripe is coupled directly into the first modulator stripe without being combined with the light the other laser stripes in an intervening optical channel waveguide. Likewise, the light exiting from the second laser stripe is coupled directly into the second modulator stripe without being combined with the light from the other laser stripes in an intervening optical channel waveguide. Similarly, the light exiting from the third laser stripe is coupled directly into the third modulator stripe and the light exiting from the fourth laser stripe is coupled directly into the fourth modulator stripe.
