ABSTRACT:
A multisegment laser diode structure is presented in the form of two spaced-apart linear waveguide segments and two spaced-apart ring-like waveguide segments, arranged such that each of the ring-like segments is optically coupled to each of the linear waveguide segments. At least one of the waveguide segments includes an active lasing material. The waveguide segments are thus arranged such that four separate electrical contacts can be provided to four waveguide segments, respectively, thereby enabling separate driving of each of the waveguide segments.
