Abstract

A laser structure includes a substrate including front and back facets and a waveguide formed thereon, the waveguide includes first and second arms extending in spaced relation between the front and back facets. The first arm includes a distributed feedback (DFB) laser and/or a semiconductor optical amplifier (SOA) and the second arm includes a SOA. At, proximate to, or adjacent the front facet, first ends of the first and second arms are spaced from each other by a first distance (d1) and an anti-reflective coating is disposed over at least the first ends of the first and second arms. At, proximate to, or adjacent the back facet, second ends of the first and second arms are spaced from each other by a second distance (d2). The laser structure is configured or includes additional structure whereupon light propagating in the first arm is coupled to the second arm.
