1989 DeTemple, Thomas A. Swanson, Paul David 2011-05-07T12:17:34Z 2011-05-07T12:17:34Z 10000-01-01 Impurity induced layer disorder-delineated buried channel optical waveguide non-rectilinear routing structures are found to have loss properties equal to or better than other planar optical waveguides. With 3 dB loss angles of 3$\sp\circ$, for simple abrupt bends, and 7$\sp\circ$, for modified abrupt bends, and 3 dB transition lengths of $\sim$300 $\mu$m for S bends with a 100 $\mu$m offset, these waveguides are capable of handling the routing requirements for many opto-electronic integrated circuit applications. A previously uncharacterized electro-absorption effect in a single quantum well graded barrier laser heterostructure was investigated as a means of providing electro-optic modulation and detection. This electroabsorption effect produced a change of over 100 cm$\sp{-1}$ in the modal absorption coefficient with less than a volt change in bias. Based on these findings, the feasibility of using a single heterostructure for the integration of multiple optical devices is addressed. Made available in DSpace on 2011-05-07T12:17:34Z (GMT).
