“…Gaussian beam propogation and theoretical calculation of coupling efficiency: We describe the Gaussian beam outgoing from fiber end and the coupling characteristic between a single-mode fiber and waveguide. In order to calculate the coupling efficiency and alignment tolerance, the Gaussian approximation is adopted, which is sufficient to calculate coupling characteristics (Saruwatari and Nawata, 1979).…”

Problem statement: Advanced optoelectronic devices are a kind of key and basic components for next generation communication, untouched sensor, medical testing. They have lots of advantages including greater communication performance, larger capacity, and more fixable form. But light coupling and package structure seriously affects performance of optoelectronic devices. So a lot of attaching methods were proposed to package optoelectronic devices. A popular method which was widely used is a UV epoxy adhesive which can solidify the coupling interface with high mechanical strength and submicron displacement. In order to obtain high coupling efficiency, coupling approximation after adhesive is needed. Approach: In this study, firstly, the light coupling model was introduced. Then light beam propagation mode after adhesive with the same refractive index as that of light path was presented and the function modeling of couple model was derived. Finally, a slantedplane structure of interface was considered and coupling approximation after adhesive was calculated. Results: Simulations and experimental results indicate that theoretical coupling efficiency and measured coupling efficiency agree with very well and the couple loss decrease about 0.4dB after adhesive. Conclusion: The matching adhesive could obviously increase the coupling efficiency and the approximation function could realize to predict the variation of coupling efficiency before or after adhesive accurately.

“…3, the normalized frequency V can take values between 1.9 \V\ 2.4 (Saruwatari and Nawata 1979). The mode-field radius is defined as the distance from the fiber axis where the power density has its maximum value down to the radius value where the power has dropped to 1=e 2 (13.5 %).…”

In modern optical communication systems, it is of the highest importance to transmit as much optical power from the transmitter to the receiver. It seems that future systems will not be that strongly dependent on good optical waveguides. Actually, even after 25 years of existence of low-loss glass fibers, the coupling efficiency remains the biggest concern of the system engineers. In this chapter, the most important principles of the optical coupling that are relevant for engineers working with this topic are discussed.

Abstract:In this paper we present the fabrication of optical mode field adaptors for fiber optical communications using fiber splicing machine in special newly developed modus. We developed mode field transformers with radii from 5 m to 80 m the end of standard singlemode and multimode glass fibers, characterized by far field and near field methods. Easy and reliable fabrication of the radii with low standard deviation = 0.16-0.97 m or better than 3,2% relative to the mean radius has been achieved.
