WebThe design of a coupling between a semiconductor laser and a single-mode fiber, or between any two optical or acoustical elements that support Gaussian modes, is presented as a trade-off among coupling efficiency Ta, offset misalignment tolerance de, and angular misalignment tolerance θe. We show that these three parameters are subject to a trade … WebThe FCE of the single-mode Gaussian beam (n = 0,m = 0) is illustrated in all the figures as a comparison and reported that multimode beams are superior to the Gaussian beam for improving the coupling efficiency. It is also concluded that the FCE increases when the number of modes, wavelength, and the source size increase.

WebSep 16, 2012 · We demonstrate experimentally the procedure of coupling of a stochastic electromagnetic Gaussian Schell-model (EGSM) beam into a single-mode optical fiber. We find that the coupling efficiency depends closely on the coherence and polarization properties of the EGSM beam, which is consistent with theoretical prediction.
