An optical package having a top and bottom orientation and comprising: (a) a platform defining a V-groove with walls of a certain pitch; (b) a first optical component having a reference surface and two sides, each side being beveled at the certain pitch outwardly from the reference surface, the first optical component having a first optical axis, the first optical component being disposed in the V-groove such that the reference surface faces downward and the sides are in parallel contact with the walls of the V-groove; and (c) a second optical component having an outer periphery with at least two contact points and a second optical axis, the second optical component being disposed in the V-groove such that the contact points contact the walls of the V-groove and the second optical axis is coaxial with the first optical axis.

Optical bench having V-groove for aligning optical components

The present invention relates to a technique for fabricating a mechanical or visual alignment fiducial on a laser die particularly adapted for application with a laser die that is a buried structure edge emitting laser. In fabricating the device, the fiducial and the active mesa are formed in the same photolithography patterning step, using conventional techniques. The active is then buried with regrowth layers. The regrowth layers are subsequently selectively etched to expose the fiducial, leaving the active region protected and buried.

Method for fabricating fiducials for passive alignment of opto-electronic devices

A method of qualifying a ferrule assembly as being adequate to make physical contact upon mating, the method comprising approving the ferrule assembly if an undercut of the ferrule assembly does not exceed a maximum allowable undercut based on ferrule deformation at a particular compressive load and apex offset.

Method of determining likelihood of optical fiber connector making positive contact
