Title: The Innovations of Alfred Phillips, Jr.
Introduction
Alfred Phillips, Jr. is a notable inventor based in Wappingers Falls, NY (US). He holds a total of six patents, showcasing his contributions to the field of laser technology. His work has significantly advanced the capabilities and performance of laser systems.
Latest Patents
One of his latest patents is the "Single Metal Level Laser Array." This invention describes a laser array that incorporates a large number of lasers manufactured on a single metal level. The design shortens the cavity length of the lasers, allowing for metal lands or traces to be placed adjacent to the rear facets of the laser for eventual interconnection with pads. Remarkably, this reduction in cavity length does not compromise the performance or characteristics of the lasers, ensuring that adjacent lasers maintain similar performance levels.
Another significant patent is the "Semiconductor Ridge Waveguide Laser with Asymmetrical Cladding." This semiconductor laser features a high value of horizontal far-field. The structure includes a substrate, a lower cladding layer made of AlGaAs, an active layer, and an upper cladding layer also composed of AlGaAs. The upper cladding layer is uniquely designed with a raised ridge portion, which is formed by etching through a mask. The aluminum mole concentration in the lower cladding layer exceeds that of the upper cladding layer, which effectively directs the optical mode towards the upper cladding layer. This design enhances lateral waveguide confinement, resulting in a high horizontal far-field.
