Title:
APPARATUS AND METHOD FOR CELL CALIBRATION OF OPTICAL SWITCH MATRIX
Document Type and Number:
WIPO Patent Application WO/2018/141084
Kind Code:
A1
Abstract:
A system and method for cell calibration of a switch matrix are provided. The optical switch matrix includes a plurality of switch cells comprising M input switch cells, N output switch cells, and a plurality of intermediate switch cells. Each one of the plurality of switch cells has at least one input waveguide and at least one output waveguide. A plurality of intermediate photodetectors are provided. Each intermediate photodetector is optically coupled to an output waveguide of one of the plurality of intermediate switch cells such that no more than two optically coupled output waveguides uniquely define a single light path from one of the M input switch cells to one of the N output switch cells. The method includes providing light to a selected one of the M input switch cells, and calibrating the intermediate switch cells located along a first light path extending from the selected M input switch cell. The first light path includes output waveguides of not more than two intermediate switch cells. These output waveguides uniquely define the first light path.
