Title: Innovations of Antonino Francesco Castiglia
Introduction
Antonino Francesco Castiglia is a notable inventor based in Schlieren, Switzerland. He has made significant contributions to the field of semiconductor laser technology, holding a total of four patents. His work focuses on improving the performance and efficiency of laser diodes and superluminescent diodes.
Latest Patents
One of his latest patents is for an edge-emitting laser diode with improved power stability. This invention features a semiconductor laser diode chip with mutually opposed front and back end facet mirrors. The design includes first and second ridges that extend between the chip end facets, defining first and second waveguides in an active region layer. This innovation allows for the formation of low and high slope efficiency laser diodes that can be independently driven by respective electrode pairs. The chip incorporates two laser diodes sharing a common heterostructure, one optimized for low power operation with good power stability, and the other for high wall plug efficiency at higher output powers.
Another significant patent involves superluminescent diodes and diode modules. This invention provides superluminescent light-emitting diode (SLED) devices and modules. A multi-wavelength SLED device is created by sequentially depositing adjacent epitaxial stacks onto a substrate to form a monolithic chip structure. Each epitaxial stack consists of n-type layers, active layers, and p-type layers. A ridge is formed in the p-type layers to induce a waveguiding region in the active layers. The SLED devices and modules are designed for applications in projection, endoscopic imaging, fundus imaging, and optical coherence tomography systems.
