"Semiconductor laser dynamics induced by optical feedback for photonic " by Bairun Nie - Vimarsana News

"Semiconductor laser dynamics induced by optical feedback for photonic " by Bairun Nie

As one of the most widely used light sources today, semiconductor lasers (SLs) are an important part of many optical systems, especially for sensing, communications, metrology, and storage applications. SLs have the advantages of small size, easy integration, and miniaturization. The massification of electronic devices has furthered this agenda, allowing the creation of portable systems capable of supporting optical sensing systems. Essentially, SLs are inherently nonlinear devices, in nonlinear systems, the folding and stretching behaviors of variables result in di↵erent dynamical routes. I...

The U.S. Patent Office published a 2nd Apple Ring patent today that uses a Self-Mixing Interferometry Sensor-based Gesture System - Vimarsana News

The U.S. Patent Office published a 2nd Apple Ring patent today that uses a Self-Mixing Interferometry Sensor-based Gesture System

Today the US Patent & Trademark Office published a second patent application from Apple relating to their smart ring project, this time using an alternative methodology than the first patent that we posted today. Apple's different methodology introduces a self-mixing interferometry (SMI) sensor-based gesture input system. The majority of the invention relates to a smart ring being used alone or in pairs, with or without an Apple Pencil for AR, VR and MR applications.
