Title: Innovations of Eun Deok Sim
Introduction
Eun Deok Sim is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of laser technology, holding a total of 12 patents. His work focuses on advancements in laser diodes, which have applications in various electronic and telecommunications systems.
Latest Patents
One of his latest innovations is the self-pulsating laser diode. This invention includes a distributed feedback (DFB) section that serves as a reflector, a gain section connected to the DFB section with an as-cleaved facet at one end, and a phase control section interposed between the DFB and gain sections. Additionally, it features an external radio frequency (RF) input portion that applies an external RF signal to at least one of the DFB and gain sections.
Another notable patent is the laser diode generating passive mode locking, which does not require a non-linear sector of a saturable absorber (SA). This laser diode includes a DFB sector serving as a reflector and a gain sector connected to it. When a current less than the threshold current is applied to the DFB sector, passive mode locking occurs swiftly, simplifying the manufacturing process and effectively extending the frequency variable region compared to using an SA.
