| Abstract: | Coupling between laser diode and single mode optical fiber has been studied by using Gaussian beam approximation. a general formular for caculating coupling efficiency of two Gaussian mode is derived under the condition of coexistence of lateral and angular misalignments. In a few special cases this formula is coincident with the previous formulae. |
