ABSTRACT:
A mount for supporting a silicon v-groove array that contains delicate opal fibers. Optical fibers are arranged in a planar silicon v-groove array to form a focal plane array, which is connected to a first L-bracket. The focal plane array and the first L-bracket combination are attached to a second L-bracket via a shock/vibration isolation pad. The second L-bracket includes an extended cylinder which is threaded so that a strain relief can be screwed directly into the second L-bracket and the fibers extending out the first L-bracket can be fed through the second L-bracket and directly into a monocoil. The second L-bracket also includes space to attach front, side and top covers over the focal plane array. In a related method, the silicon v-groove array is epoxied to the first L-bracket. After preparation of the focal plane array, e.g. polishing of the fibers, is completed, the focal plane array/first bracket combination is connected to the second L-bracket, with the pad therebetween. The covers are then attached to the L-bracket.
