Which is Better For Broadband Light Source? TD-OCT or SD-OCT?

-

Optical coherence tomography (OCT) is a rapidly growing, advanced technology that has transformed ophthalmology practice. OCT is widely employed in the medical profession. It is based on low-coherence interferometry, and a focused probe may be utilized to acquire the reflectivity profile of material along an optical axis.

There are two types of OCT imaging: TD-OCT and SD-OCT. Both have their own advantages and disadvantages, so which one is better for broadband light source imaging?

Which is Better For Broadband Light Source? TD-OCT or SD-OCT?

TD-OCT uses a time-domain imaging method, which means that it captures light that is scattered at different depths in the tissue. This results in a more detailed image, but it also takes longer to capture. SD-OCT uses a spectral-domain imaging method,  it captures light that is scattered at different wavelengths. This results in a less detailed image, but it is much faster.

So, which one is better? It depends on what you need. If you need a detailed image, then TD-OCT is the better choice. If you need a faster image, then SD-OCT is the better choice. To know the reasons to choose SD-OCT over TD-OCT for broadband light source, check our full blog: Which is Better For Broadband Light Source? TD-OCT or SD-OCT?

Explained: How Does FP Laser Work?

-
Image
The Fabry Perot– FP laser , also known as the Fabry Perot Interferometer (FPI), is a type of laser that is widely used in the telecommunications industry, astronomy, and other fields. This laser’s primary application is for low-data-rate short-distance transmission over distances of up to 20 kilometers. It should be noted that the FP laser is a more advanced version or substitute for the DFB (Distributed Feedback) laser. The spectrum width is the fundamental distinction between DFB and Fabry Perot lasers. On the one hand, the Fabry Perot laser has a wide spectrum width and is a multi-longitudinal mode laser, whereas the DFB laser has a narrow spectrum width and is a single longitudinal mode laser. To know the working of FP laser, Check our blog .

DFB Laser vs. DBR Laser: 4 Major Differences

Image
The late 1990s to the early 2000s telecom revolution prompted laser manufacturers to innovate and design more varieties of lasers to meet the growing demand in telecom applications. One of the best ways to meet the need for low signal lasers is to use distributed feedback lasers (DFB lasers). These lasers have not only contributed to addressing the needs of the telecommunications industry but have also caused the disappearance of DBR lasers (Distributed Bragg Reflectors) from the market. In this post, we'll look at the differences between DFB lasers and DBR lasers. But before that, we will take a quick look at what DFB laser is and what DBR laser is. What Is A DFB Laser? A DFB laser is a type of diode laser that generates resonance and oscillation in the cavity using diffraction gratings rather than mirrors. A distributed feedback (DFB) laser's purpose is to sharpen the output of conventional Fabry-Perot lasers . The substitution of mirrors with grating offers DFB la...

Distributed Feedback Laser: Working and Its Importance

Image
In recent years, we've been introduced to various advanced lasers that have been developed to address the growing demand for communication. The DFB laser is one such name on the list. DFB Lasers produce a single-mode output and are much more stable than Fabry-Perot Lasers and Distributed Bragg Reflector Lasers. A diffraction grating placed along the active region of the chip can accomplish this. Distributed feedback lasers are commonly used as a light source for metro, long-distance, and underwater applications due to their narrow spectral width and wavelength stability. In this blog, we'll look at how distributed feedback lasers work and how important they are. But first, let us define the DFB laser and its various types. What Is DFB Laser and What Are Its Different Types? A DFB laser is a narrow linewidth laser diode or optical fiber laser in which the grating occurs throughout the cavity rather than just at the two ends. The diode's structure creates a one-dime...
