Title: Innovations of Rajiv Agarwal
Introduction
Rajiv Agarwal is a notable inventor based in Calcutta, India. He has made significant contributions to the field of laser technology, holding a total of 3 patents. His work focuses on enhancing the performance and reliability of laser diodes.
Latest Patents
One of his latest patents is the "Laser diode array with built-in current and voltage surge protection." This invention provides protection from current and voltage spikes for a laser array by attaching a reverse diode laser array to shared contact pads before the first laser array is bonded to those pads. This arrangement ensures surge protection even during the fabrication of the laser package, where device failure can occur due to power surges before the surge protection circuitry is in place. Surge protection is achieved by having a reverse diode of the reverse diode array electrically in parallel with a corresponding laser diode of the protected array when activated.
Another significant patent is the "Reduced mode laser and method of fabrication." This invention involves a reduced, lateral mode laser diode that is fabricated using a self-aligning process. This process produces a well-controlled weakly index-guided waveguide with strong current confinement. The structure includes ion implants for controlling current injection into the active region from the top of the ridge. The number of modes may be reduced to unity, resulting in a single lateral mode laser. A laser diode array is fabricated in the same manner.
