Abstract

An optical device includes a surface-mountable optical component with a base member having a recess filled with a transparent filler and a VCSEL element arranged in the recess. A receptacle is attached to the surface-mountable optical component. The receptacle is for receiving an optical fiber to optically connect the VCSEL element to the optical fiber. Accordingly, an inexpensive way of coupling a VCSEL element with an optical fiber is provided. In particular, the surface-mountable component can be produced using a high volume production so that the overall costs of the optical device are reduced, even if the receptacle is produced in lower numbers due to varying requirements in the way that the VCSEL will be coupled to an optical fiber.
