“…It is also commonly employed in optical communications due to the increased use of PCFs. Two types of PCFs were fused into an optical coupler with the fused biconical tapered (FBT) method [19]. SMF-28 fiber's efficiency was one of the obstacles to its commercialization.…”

In a fiber optic communication system, optical fiber is used as a transmission medium consisting of a flexible filament that guides the optical signal to be transmitted from the transmitter to the receiver or vice versa. Like any other communication medium, the optical fiber cable faces some losses that can be caused by the material and length of the fiber. One of the main reasons for losses in optical communication systems is misalignment during the fiber to fiber joining process. This type of loss is also known as coupling loss, which is caused by an imperfect physical connection between two fibers. The coupling losses are most often caused by three misalignment issues: end gap displacement, lateral displacement, and angular displacement. The main goal of this article is to investigate coupling loss caused by misalignment in optical fiber using the Modicom 6 module. Before we can find a way to reduce the coupling losses in the fiber optic system, we need to have a concrete idea about the nature of coupling losses due to misalignment. An ideal fiber coupler should not lose light and should be insensitive to light dispersion.

“…Research into the field of photonic crystal fiber (PCF) has attracted a great deal of interest in recent years due to the novel and extended range of waveguide properties [1][2][3][4].These properties include: endlessly single-mode operation, anomalous dispersion down to visible wavelengths, and high or low nonlinearities-all of which can be achieved by appropriate design of the holes and rely upon the large occupied-space ratio between air and silica [5]. Rare earth-doped PCF was found many of these novel features.…”

We have demonstrated a low threshold all fiber laser based on a 9.68 m-long small core Erbium doped photonic crystal fiber (PCF) and also presented results from two separate device experiments. The threshold and maximum output power of the laser are 6.72 mW and 82.6 mW, respectively. Fiber loop mirrors is used as resonator mirrors. The overall system is all-fibered and with low threshold. The PCF we used as gain medium with 9.68 m long, 3.34 μm mode diameter, 0.143 numerical aperture, 1000 ppm doped concentration, 545 dB/km transmission attenuation coefficient to 1310 nm laser. A single-mode diode laser, centered at 980 nm, was used as pump source and the maximum power was 400 mW.
