APPARATUS FOR MODULATING PULSE USING A DEVICE FOR DELAYING LIGHT WAVE

摘要

An apparatus for modulating pulse using a light wave delaying device is provided to form shuttle light transmission paths using passive optical elements(optical simulator and optical mirror), thereby reducing the size of the apparatus and reducing manufacturing cost. An apparatus for modulating pulse using a device for delaying light wave comprises the followings: an optical simulator(10) having an input port for inputting an optical signal, a delay port for delaying the optical signal, and an output port for outputting the optical signal; an optical delay unit(20) having an optical delay unit to be connected to the delay port; a first switch for switching signal input; an optical converter for converting a signal passed through the first switch into an optical signal; a photoelectric converter for recovering an optical signal delayed in the optical delay unit; and a second switch.
