Abstract
A method for providing an optical interface with at least one optical coupling structure for a packaged optical device is described. The at least one optical coupling structure may be, for example, wave-guides and/or microlenses. The packaged optical device includes an external alignment structure. The external alignment structure has a support means with at least one hole and at least one alignment feature. The method includes providing optical encapsulate material in the hole of the support means. Optical coupling structures, such as wave-guides or microlenses, may be provided into the encapsulation at a well-defined position relative to the at least one alignment feature of the external alignment structure. By providing the optical coupling structures directly in the material comprised in the encapsulation, a high degree of alignment accuracy is obtained.
