VCSELs (Vertical-Cavity Surface-Emitting Lasers) were invented in the mid-1980s. However, in a relatively short period of time, VCSELs established a reputation as a superior technology for short-distance applications such as fiber channel, Ethernet, and intra-systems communications. Over the next few years, VCSELs displaced edge-emitter lasers as the technology of choice for short-range datacom and local […]

It is not uncommon to see the use of superluminescent diodes for optical coherence tomography. Because of the unique properties of superluminescent diodes (SLD), such as low coherence light, high brightness, minimal spectral ripple, and a broad, smooth optical output spectrum, it is the preferred and perfect solution for optical coherence tomography. However, in order […]
From ancient times to the present day, mankind has continuously invented new technologies and tools for comfort and progression. Be it fire, the wheel, electricity, computers, the internet, mobile devices, or the latest LiDAR laser technology. All of these inventions have made significant contributions to mankind’s evolution and, at the same time, have become the […]
Several types of lasers have been invented in the last few decades to tackle the rising need for communication. One such laser is called the DFB laser. It is a type of narrow linewidth laser diode or an optical fiber laser where the grating generally happens along the cavity, and not just at the two ends. […]
