The 21st century has witnessed a significant revolution in imaging techniques. Continuous innovation in this area has introduced many advanced technologies over the last two decades, including TD-OCT (Time-Domain Optical Coherence Tomography), SD-OCT (Spectral-Domain Optical Coherence Tomography), and SS-OCT (Swept Source OCT). Swept Source is a type of laser incorporated in the device. Swept Source […]
Semiconductor lasers such as FP, DFB, and VCSEL are essential devices for regulating and improving the Internet and communication sector worldwide. Their outstanding properties, such as high efficiency in converting electrical energy into photons, excellent reliability, small footprint, modulation bandwidth, and low cost, have made them principal components in various communication applications. VCSEL, or Vertical […]
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. […]
Superluminescent Diodes (SLDs) are semiconductor devices that offer a unique combination of high brightness similar to laser diodes (LDs) and low coherence like light-emitting diodes (LEDs). This special combination of properties makes SLDs an essential technology for a wide range of applications, particularly in optical sensing systems such as Optical Coherence Tomography (OCT) and fiber-optic […]
Superluminescent diodes (SLDs) represent an exciting and advanced form of semiconductor technology that blends the best features of light-emitting diodes (LEDs) and laser diodes (LDs). SLDs are designed to emit low-coherence light with a broad spectrum similar to an LED, but they also offer high brightness levels typically associated with laser diodes. This combination of […]
Semiconductor Optical Amplifiers are essentially electronic components leveraged in telecommunication to compensate for the loss of signal. SOAs work on the basis of a gain medium; in layman’s terms, they help in “gaining” the lost signal input and ensure complete delivery of the signal. A semiconductor optical amplifier can be thought of as a laser […]
Optical fiber communication has become an integral part of modern communication networks. Several transmission bands, from the original O-band amplifier to the U / XL band, are defined and standardized in fiber optic communication systems. Optical amplifiers are also used at other places in a network, such as within an optical switching node to compensate […]
Advancements in science and technology have significantly impacted how the world functions, and one such breakthrough is the development of swept source technology. Introduced in 2012 for optical coherence tomography (OCT), swept source has revolutionized the field of medical ophthalmology. It has empowered ophthalmologists worldwide to diagnose and treat optical problems like glaucoma with relative […]
