Abstract:
An integrated two-dimensional tunable filter array for a matrix of fiber optic input/output light channels incorporating microelectromechanical (MEMS) tunable filters comprising:a first semiconductor substrate having a plurality of guiding grooves for said input light channels aligned in a predetermined plane parallel to the major surfaces of said substrate extending from an external portion of said substrate and terminating in an interior array in said substrate in 45Â° reflecting surfaces to cause light beams of inserted said light channels in said guiding grooves to be reflected 90Â° from said plane; a second semiconductive chip bonded to said first substrate and incorporating an array of said tunable filters for respectively receiving said reflected light beams; a third semiconductive substrate bonded to said second chip and having an array of guiding grooves having axes perpendicular to said major surfaces of said third semiconductive substrate for insertion of output light channels, such array matching and being passively aligned with said filter array.
