A planar diode and method of making the same employing only one mask. The diode is formed by coating a substrate with an oxide, removing a central portion of the oxide to define a window through which dopants are diffused. The substrate is given a Ni/Au plating to provide ohmic contact surfaces, and the oxide on the periphery of the window is coated with a polyimide passivating agent overlying the P/N junction.

An optical fiber line arranging guide groove capable of sensing optical signals is provided for detecting the status of optical signals in the optical fiber line. Through an optical detection circuit and a display element, the connection status of optical signals for the optical fiber line in the optical fiber line arranging guide groove is determined.

An optical path switching device is provided. The optical path switching device utilizes the electro-optic effect to apply an electric field on different reflective elements without moving an input/output end of optical signal or reflective elements. Thus, the reflective elements reflect optical beams to control travel paths of the optical beams, so as to switch the optical paths in the absence of mechanical motion.
