The Principal Types of Semiconductor Optical Amplifiers Applications

-

There has been significant growth in optical fiber communication networks' deployment and capability in the past twenty-five years. The development of modern optoelectronic technologies that can be used to take advantage of the enormous optical fiber bandwidth has made this growth possible.

In this piece, we have reviewed the three primary areas where SOAs are used. Let us understand it in brief.

Types of Semiconductor Optical Amplifier Applications

The key applications of SOAs in optical communication systems can be categorized into three areas: 

1. As a Booster Amplifier

2. As a Pre Amplifier

3. As an In-line Amplifier

Now let us understand each of these amplifiers and its role in brief.

1. Booster Amplifiers

A post-amplifier or booster amplifier is used to increase the laser power of the transmitter. 

In an optical transmitter, boosting laser power allows creating medium-haul connections with an increased transmission wavelength. 

These links are actually made up of optical fiber between the transmitter and the receiver. Since this involves no active components in the transmission link, it improves reliability and performance.

2. Preamplifier 

A preamplifier is used to enhance the sensitivity of the receiver. The rise in power level will improve the sensitivity of the receiver. This enables the creation of longer, unrepeated links. The preamplifier circuit receiver consists of an optical preamplifier, a photodiode accompanied by post-detection circuitry and a decision circuit, and a narrowband optical filter.

3. In-line Amplifier

An in-line amplifier is used to overcome the need for optical regeneration to compensate for medium- and long-haul transmission losses.

The key benefits of in-line SOAs are data rate clarity and modulation format, bidirectionality, WDM capability, easy operation mode, low power consumption, and SOA injection.

The introduction of optical amplifiers into optical communication connections will increase the device's efficiency and reduce costs.

These are the three principal areas where SOAs are used. The next section describes the nonlinearities of the Semiconductor optical amplifier– a basis of many SOA applications.

The Future of Semiconductor Optical Amplifier

As it is such a highly flexible component that can be used for different amplification and routing functions in telecommunications, the Semiconductor Optical Amplifier (SOA) is still the subject of much current research.

Commercialized SOAs are now widely available for advanced optical systems for central, metro, and possibly all types of access applications and are rapidly becoming a cost-effective optical amplification solution.

The capabilities of SOA include nearly unlimited bandwidth for carrying communication services of almost any kind and complete an openness that enables capacity upgrades to the terminal and versatile channel routing. The optical amplifier has made many of the developments possible in optical networks.

Therefore, SOAs will continue to create new interest in all-optical communication systems for a wide range of applications in the future and may well become the device of choice for use.

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

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

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...
