| Research Abstract |
We consider some possible applications including optical interconnects, parallel fiberoptic subsystems, and so on by featuring high power capabilities and largely extending 2-D arrays, For the purpose of realizing coherent arrays, coherent coupling of these arrayed lasers has been tried by using a talbot cavity and phase compensation is considered. It is pointed out that 2-D arrays are more suitable to make a coherent array than a linear configuration, since we can take the advantage of 2-D symmetry. The research activity is now forwarded to monolithic integration of SE laser based optical circuits by taking the advantage of its small cavity dimension. Densely packed arrays have also been demonstrated for the purpose of making high power lasers and coherent arrays.
