摘要： A sampling optical pulse generation unit emits a sampling optical pulse. The sampling optical pulse has a period different from a predetermined offset time to integral multiplication of a clock period of a data signal, and the data signal modulates an optical signal of a monitoring target. An optical sampling unit performs sampling of the optical signal of the monitoring target using an electroabsorption optical modulator. The electroabsorption optical modulator has a characteristic in which an absorption index is changed with respect to light propagating through an optical path according to a level of an electric field. The optical signal of the monitoring target is input into one of two optical terminals of the electroabsorption optical modulator. The sampling optical pulse is input into another of the two optical terminals through a photocoupler. The absorption index with respect to the optical signal of the monitoring target is lowered by generating a mutual absorption saturation characteristic of the electroabsorption optical modulator when the sampling optical pulse is supplied, and the sampling of the optical signal of the monitoring target is performed to output an optical pulse signal from the other of the two optical terminals through the photocoupler.

摘要： A common reference signal is applied from the same reference signal generating portion to a reference signal input terminal of a signal under test generator and a reference signal input terminal of a sampling signal generator circuit. A sampling frequency is set to the sampling signal generator circuit such that a desired delay time can be obtained relevant to a phase of a signal under test. In the sampling signal generator circuit, the sampling signal having a cycle that corresponds to the sampling frequency is generated based on the common reference signal and the sampling frequency. A repetition cycle of the signal under test and a repetition cycle of the sampling signal are set based on a cycle of the common reference signal so that the repetition cycle of the sampling signal can be set independently of the repetition cycle of the signal under test.

摘要： A nonlinear optical crystal is composed of 2-adamantyl-5-nitorpyridine (AANP) allowing the type 2 phase matching to the sampling light and a measuring object light, emitting a sum frequency light of the measuring object light and the sampling light, with the polarization directions thereof being perpendicular to each other, when the sampling light and measuring object light multiplexed by a multiplexer are entered. When the sum frequency light is emitted through the nonlinear optical crystal, a control portion controls the polarization direction of the sampling light so as to be parallel to a predetermined reference axis located within a plane perpendicular to a phase matching direction of the nonlinear optical crystal. The predetermined reference axis is a single axis maintaining parallelism with the crystal axis of the nonlinear optical crystal even if the wavelength of the inputted light is changed.

摘要： A sampling light source generates a pulse sequence of sampling light having a pulse width smaller than that of target light and a single plane of polarization. A polarization beam splitting unit splits each of the sampling light output from the sampling light source, and the target light into two light components having planes of polarization shifted 90.degree. from each other, multiplexes each pair of split sampling and target light components having planes of polarization shifted 90.degree. from each other, and outputs the respective multiplexed light components to different optical paths. A pair of nonlinear optical members each generate a cross-correlation signal based on the sampling and target light components output from the polarization beam splitting unit to each optical path and having planes of polarization shifted 90.degree. from each other as sum frequency light. A pair of photodetectors each convert the sum frequency light output from each of the pair of nonlinear optical members into an electrical signal. A signal processing unit adds the electrical signals output from the pair of photodetectors, processes the resultant electrical signal, and displays its pulse waveform. With this operation, the pulse waveform of the target light can be accurately measured regardless of variations in the polarized state of the target light.

摘要： A first tunable wavelength pulse light source is driven by a reference signal to emit a first optical pulse. An optical demultiplexer demultiplexes a first optical pulse emitted from the first pulse light source into a reference optical pulse and an incident optical pulse to be sent into an object to be measured. An optical multiplexer multiplexes the reference optical pulse and an outgoing optical pulse passing through the object to output multiplexed light. A second pulse light source generates a second optical pulse which is synchronous with the first optical pulse and delays a predetermined time for each period of the first optical pulse. A sampling unit receives the multiplexed light and the second optical pulse to obtain an optical pulse train signal proportional to the intensity of the multiplexed light obtained in synchronism with the second optical pulse. From the optical pulse train signal from the sampling unit, a signal processor obtains an envelope formed by peaks of individual optical pulses forming the optical pulse train. The wavelength dispersion of the object is obtained by measuring the delay time of the outgoing optical pulse passing through the object on the basis of intervals between the peaks of the envelope.
