Title: | Out-of-plane optical coupling between an elliptical Gaussian beam and an angled single-mode fiber | Authors: | Chen, W.T. LON A. WANG |
Keywords: | Angled fiber; Elliptical Gaussian beam; Optical coupling | Issue Date: | 1998 | Journal Volume: | 16 | Journal Issue: | 9 | Start page/Pages: | 1589-1595 | Source: | Journal of Lightwave Technology | Abstract: | An approximate analytical model is developed for calculating the out-of-plane coupling efficiency between an elliptical Gaussian beam from a laser diode and an angled singlemode fiber. The simulation results obtained from the model indicate that when a laser diode has no tilt the coupling efficiency varies with relative rotation angle at a period of π rather than remains constant, and the period changes from π toward 2π as the tilt angle of laser diode increases. A proof-of-principle experiment is performed to demonstrate the validity of the model as the elliptical factor becomes large. Potential applications by employing the model are discussed. |
