Our planet is connected by communications technology. Right now, around 66.2% of people worldwide use the internet. To account for the ever-increasing demands of the industry, we need more and more efficient technologies. Optical interconnects fit that bill. Read on...
In optical communications, there is a demand for high-capacity transmission systems. This has led to the creation of sophisticated technologies, like Wavelength Division Multiplexing (WDM). WDM stands out as a pivotal strategy, enabling the simultaneous transmission...
In optical communications, erbium-doped fiber amplifiers (EDFAs) are pivotal for their amplification capabilities. However, non-uniform gain profiles often limit their performance across desired wavelength ranges. This limitation can be addressed by integrating gain...
In the field of optics engineering, the ability to isolate specific wavelengths of light is crucial for various applications, including infrared (IR) sensing. Edge and band pass filters play a vital role in achieving this isolation, allowing for the detection and...
Infrared (IR) sensing applications are becoming more valuable in a wide range of scientific fields, including thermal imaging, biomedical sensing, and gas detection. However, the accuracy and efficiency of IR sensing can be significantly enhanced through the use of...
IR sensing technology harnesses the power of infrared radiations – which are invisible to the human eye – for various scientific and industrial applications. It leverages specially designed IR sensors and filters to detect energy levels and monitor changes in the...
Etalons are a type of Fabry–Pérot interferometer – an optical cavity made from two parallel reflecting surfaces. They can act as optical filters since only the frequencies matched to the resonant frequencies of the cavity can pass through the cavity. As a result, they...
As voice, video, and data traffic continue to increase, improving the flexibility and capacity of optical networks is a pressing challenge. Multiband optical filters have been used in applications as varied as astronomy, fluorescence spectroscopy, and 3D cinema. The...
The rapid expansion of the World Wide Web and increased connectivity requirements have generated an explosion in optical communication systems. In optical fiber-based communications, optical signals are transported on a light wave. Each wavelength (or frequency) of...
The demands placed on networks by voice, video and data are increasing exponentially. Thus, service providers require more bandwidth and higher transmission speeds. However, deploying fiber cabling for each service is costly. Transceiver-based solutions add more...
Long pass filters, sometimes referred to as long pass edge filters, are designed to transmit wavelengths within a given wavelength range. This band is defined by the filter’s cut-on edge which essentially blocks frequencies shorter than the specified edge wavelength....
Dichroic filters are designed to selectively allow wavelengths within a specific transmission band to pass through while reflecting all other colors and for beam steering purposes. They are particularly useful in optical applications where the detector is...
