Abstract: PURPOSE:To obtain an output signal at a frequency within a specified range even when an input signal inputted to an PLL circuit reaches any state by providing a diode and a resistor to the PLL circuit so as to always limit an output voltage amplitude of a low pass filter. CONSTITUTION:The PLL circuit is provided with diodes 5, 6 limiting an output voltage of a low pass filter 4, a voltage source 7 to set a limit level of the diodes 5, 6 for the output voltage and a resistor 8 limiting a current flowing to the diodes 5, 6.

Abstract: PURPOSE:To obtain a large branching angle with small loss by providing at least two high-refractive-index parts nearby a terminal part of the 1st optical waveguide and forming a recessed part which has at least two reflecting surfaces in the branching part of the optical waveguide. CONSTITUTION:Light propagated in the 1st optical waveguide 1 has a light power distribution having its peak in the center as shown by A. This light is propagated in the optical waveguide 1 toward the terminal and the light power is converged on the high-refractive-index parts 5a and 5b, so two peaks appear in the light power distribution as shown by B. Then, the light is nearly separated at the terminal of the optical waveguide 1 into two light waves which each have one peak as shown by C; and one half wave is reflected by the reflecting surface 4a to travel to an optical waveguide 2 and the other half is reflected 4b to travel to an optical waveguide 3. Thus, the distribution of light power is similar at positions A, B, and C, so the light loss is small and the large branching angle is obtained.
