| 英文摘要 | A cost-effective wavelength division multiplexer and demultiplexer for use in optical communication consists of three modules, including a fiber array (20), a lens array (30) and a filter array/reflector (40). Each array is made in wafer level with very precise position control and is bonded to an adjacent wafer by conventional wafer bonding techniques. In addition to eliminating the need for active alignment in the manufacturing process of a wavelength division multiplexer (WDM) transceiver, the invention reduces the footprint of such a device to the order of a few millimeters and the process is suitable for low-cost, large quantity manufacturing. The fiber array (20) is connected to the light sources (10, 12, 14, 16), which optimally are fiber pig-tailed semiconductor lasers to enable repeatable and accurate placement in reference to the lens array (30). The input lenses (32, 34, 36, 38) are used to collimate the beams such that light traveling from them at an angle will zigzag between the reflector (49) and the filters of the filter array/reflector combination (40). In the multiplexer configuration, an output lens (39) is used to focus and couple the beams from each different laser (10, 12, 14, 16) into a fiber (18). |
