SOLUTION: A masking material layer 44 is formed on a substrate 31 which is composed of a silicon substrate 42 and a single crystal silicon device layer 43 interposing an intermediate layer 41 of silicon dioxide (Fig. A), the masking material layer 44 is patterned, a mask 45 is formed having a pattern which is the same as the flat figure of an object optical device. In this case, the face to become a mirror face is the (100) plane of a silicon crystal. The device layer 43 is vertically etched by using the mask 45 as a mask with a dry etching of reactive ion until the intermediate layer 41 is exposed (Fig.C). Thereafter, the side wall face of a mirror 4 is made to be a flat crystal face (100) by performing an anisotropic wet etching in the crystal orientation in a KOH solution for approximately 10 minutes. Then, only the intermediate layer 41 under the movable part of the optical device is removed by selectively wet-etching the intermediate layer 41 (Fig.D). COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To eliminate a directional optical coupler and to reduce the number of test light sources and detectors. SOLUTION: An input optical fiber (202), an output optical fiber (204), a pair of orientational elements (206, 208), and the detector (128) form an alignment channel in an optical switch (200). The input optical fiber (202) in each alignment channel and the output optical fiber (204) are dedicated to propagate an alignment optical beam (118) through the optical switch (200). The dedicated orientational elements (206, 208) orientate the alignment optical beam (118) from the dedicated input optical fiber (202) to the dedicated output optical fiber (204). The detector (128) receives the alignment optical beam (118) from the dedicated output optical fiber (204), and forms a signal expressing the alignment optical beam (118). The signal is transmitted to a control apparatus (130), and the control apparatus forms a corrected signal to an orientational element array. All orientational elements in the array are adjusted by the corrected signal for minimizing the loss of an optical signal power. COPYRIGHT: (C)2005,JPO&NCIPI
