Abstract

PURPOSE:To improve the coupling effect in connecting the optical fibre to the light source of such as the light emitting diode laser, by constructing the one end of the coupler approximately equal to the sectional area of the light emitting area, while the other end is tailored to such a cone form core which has the sectional area approximately equal to the optical fibre core.
