METHOD AND ARRANGEMENT FOR COUPLING A WAVE GUIDE TO A COMPONENT |
摘要 |
Optical components intended for telecommunications purposes must be manufactured and mounted with a great degree of accuracy, since a component, such as an optochip, when mounted must be coupled optically, electrically, mechanically and thermally at the same time. In order to obtain a right-angled geometry when using surface-emitting or surface-detecting components, and to obtain a reduced optical travel path and accurate fixation of an optofibre, a reflective surface (12) which slopes at an angle of 45 degrees is arranged between a light-conducting core (16) and the active surface (10) of an optochip, and the light-conducting core has been placed closer to the reflective surface by bevelling the optofibre (9) and fitting the fibre in a Vgroove and accurately fixating the fibre in the groove by means of a flat cover means (20). The aforesaid solutions relate generally to problems of a geometrical nature, but are able to provide important advantages in the arrangement of optical components in so-called optical micro-structures in comparison with earlier known techniques with regard to requirements of space, signal transmission performances and manufacturing costs.
