Title: The Innovations of Donald B Carlin
Introduction
Donald B Carlin is a notable inventor based in Robbinsville, NJ (US). He holds a total of 3 patents that showcase his contributions to the field of semiconductor technology. His work has significantly advanced the capabilities of laser systems, particularly in phase modulation and surface emitting lasers.
Latest Patents
One of Carlin's latest patents is the "Phase modulation semiconductor laser array." This invention involves a phase-locked semiconductor laser array that is dephased-locked by forming at least two p-type contacts that are electrically isolated from one another. These contacts are coupled to one side of the active region, while a single contact layer is connected to the other side. By applying the same current to the two p-type contacts, a single phase-locked far-field lobe is formed. A different current is applied to one of the contacts to create a dephased multiple lobe beam, which is then effectively received by an aperture that blocks the multiple lobes, producing a modulation effect.
Another significant patent is for "Surface emitting lasers with combined output." In this invention, surface emitting lasers are laterally aligned and coupled together, allowing their light output signals to be combined. This results in improved phase and frequency coherency, as well as narrower amplitude sidelobes. The design ensures that no more than two lasers are longitudinally aligned along the same axis, enhancing coherency compared to configurations with more than two lasers.
