A Detailed Examination of the Finite-Volume, Time-Domain Method for Maxwell's Equations

Novel semiconductor devices are monolithically defined with p-type and n-type wide bandgap material formed by impurity induced layer disordering of selected regions of multiple semiconductor layers. The devices are beneficially fabricated by simultaneously forming the n-type and p-type layer disordered regions with sufficiently abrupt transitions from disordered to as-grown material. The novel devices include a heterojunction bipolar transistor monolithically integrated with an edge emitting heterostructure laser or a surface emitting laser, a heterostructure surface emitting laser, a heterostructure surface emitting laser having active distributed feedback, devices containing multiple buried layers which are individually contacted such as p-n junction surface emitting lasers, carrier channeling devices, and "n-i-p-i" or hetero "n-i-p-i" devices, and novel interdigitated structures, such as optical detectors and distributed feedback lasers.
