An optical pulse pattern generator can generate optical pulse signals with various periods and patterns. It supplies an optical pulse from an optical pulse source (9) to a variable optical delay line circuit including cascade-connected characteristic-variable asymmetrical Mach-Zehnder interferometers (102 and 103) via an optical combiner and splitter (101). The optical pulse is fed back to the optical combiner and splitter (101) from the final stages of the cascade-connected characteristic-variable a symmetrical Mach-Zehnder interferometers (102 and 103) via an optical exclusive OR circuit (104) and optical amplifier (14). Making directional couplers with variable coupling ratio (11-1 to 11-5 and 11-7 to 11-11), and directional couplers with variable coupling ratio (11-6 and 11-12) in operation can cause the final stage of the cascade-connected characteristic-variable asymmetrical Mach-Zehnder interferometer (103) to produce a random pulse train. |

| PROBLEM TO BE SOLVED: To provide an optical switch device reduced in its packaging volume and cost by integrally forming a space switch part and an wavelength switch part. SOLUTION: An wavelength converter 121 connecting its input terminal to an optical branching unit 131 and connecting its output terminal to an optical coupler 141 acts as an wavelength conveter only when a current is injected into a semiconductor optical amplifier included in its inside, and when a current is not injected, outputs no light. Thereby the converter 121 can be allowed to act as a gate switch by turning on/off the injection current to the amplifier in the converter 121, so that the converter 121 constitutes a switch device having both of an wavelength conversion function and a space switch function. When plural wavelength converters 121 to 123 connected to one optical branching unit 131 are connected to respectively different optical couplers 141 to 143, the device can be provided with an wavelength multiplexing function.
