The invention discloses an optical-fiber all-optical code converter, comprising a temperature control circuit as well as optical-fiber Mach-Zed interferometer, heat sink, semiconductor refrigerator, thermosensitive resistor and radiator, where the interferometer is composed of two cascaded 3dB couplers on the heat sink, the relation between length difference delta L of two arms of the interferometer and generated delay time difference delta T is that delta L=c.delta T/n, where c is light velocity in vacuum and n is refractive index of optical fiber; the thermosensitive resistor is used to detect temperature of interferometer, the temperature control circuit is used to compare feedback voltage of the thermosenstive resistor with a given voltage to regulate working current of the semiconductor refrigerator, and the semiconductor refrigerator refrigerates or heat two arms of the interferometer by the heat sink.

本发明公开了一种光纤型全光码型转换器，它包括温控电路和位于密封盒内的光纤型马赫-泽德干涉仪、导热热沉、半导体制冷器、热敏电阻以及散热片；干涉仪由位于导热热沉上的二个3dB耦合器级联而成，两臂的长度差ΔL与产生的延时差ΔT之间的关系为ΔL＝c。ΔT/n，c为真空中光速，n为光纤折射率；热敏电阻用于对干涉仪的温度进行探测，温控电路用于比较热敏电阻反馈的探测电压和设定电压，对半导体制冷器的工作电流进行调节，半导体制冷器通过导热热沉对干涉仪两臂同时进行制冷或加热。
