“…Today, unfortunately, almost all gigabit optical sources operate in the near-infrared (typically 850nm or 1300nm), where PMMA and similar polymers are essentially opaque. Nevertheless, in this scenario, undistorted bit streams of 2.5Gbps over 200m of transmission length were successfully demonstrated over PMMA-GIPOF [12].…”

“…In the current optical fiber communication systems monopolized by inorganic materials, almost all types of optical fiber communication devices are built using inorganic materials. In the beginning of the 21 st century, plastic optical fiber (POF) communication systems achieved considerable progress in the field of short-range communication [1], [2]. Organic polymer fiber, as a kind of POF, has been widely used in short-distance communication and laser display in recent years.…”

We studied the optical signal amplification properties of coumarin 460 (C460) in solution. An optical signal amplification experiment was performed using a side-pumping setup. Amplification of more than 7 dB was achieved over a 13-nm spectral width in the signal wavelength range of 448-461 nm with gains above 10 dB at 448 nm and in the 455-461-nm range. The signal-to-noise ratio (SNR) of the entire band was 5.8-11.1 dB. When the solution concentration and pump energy were 0.001 M (mol/L) and 117 μJ, respectively, the optical gain reached a maximum of 12.25 dB. Thus, the gain and SNR were measured by adjusting the pump energy and solution concentration to determine the optimal concentration of coumarin 460 in methanol solution in the amplifier. Additionally, amplification of the spontaneous emission was found to seriously reduce the SNR, adversely affecting the optical gain.

“…However, improvements in the bandwidth of POF fiber can be obtained by grading the refractive index, thus introducing the so-called Graded-Index POFs (GIPOFs). Although firstly developed PMMA-GIPOFs were demonstrated to obtain very high transmission bandwidth compared to that of SI counterparts [7], the use of PMMA is not still attractive due to its strong absorption at the near-infrared (near-IR) to infrared (IR) regions. As a result, PMMA-based GIPOFs can only be used at a few wavelengths in the visible portion of the spectrum.…”
