Abstract: An assembly for coupling an optical fiber to an optical component, e.g., an axisymmetric light source such as an axisymmetric laser diode, comprises a light source connected to an optical fiber ferrule via a focusing component in the form of a micro lens element. This element is made in the form of a plate having one end face flat and the opposite end with an circular microlens. The microlens is inserted into the central opening of the ferrule and is glued to the end face of the ferrule with a UV-curable optically matched glue. An essential part of the invention is that all parts of the coupling are made from a material with the same or close coefficient of thermal expansion, and that an assembling procedure ensures optimal coupling (without losses) of the light source to the fiber due to high quality of the aspheric lens and due to a specific sequence of operations in assembling.

Abstract: A laser-diode assembly for generating a frequency-stabilized narrow-bandwidth light comprises a light source in the form of a semiconductor laser diode coupled via a first optical coupling device to one end of a first optical fiber. The other end of this fiber is coupled to a second or an output fiber via a second optical coupling device. The assembly is characterized by the fact that a long inner cavity is formed by a section of the optical system between two oppositely directed mirrors. The first mirror is applied onto the back side of the semiconductor laser diode, and the second mirror is applied onto a flat front side of one optical lens element or onto the back side of another optical lens element. These optical lens elements are parts of an optical coupling between the first and the second fibers. The first mirror completely reflects the entire light incident onto this mirror, whereas the second mirror reflects a major part of the light, e.g., about 90% and passes only a small part, e.g.
