Definitions
- the phase modulator 1 for example, a phase modulator using an electro-optical effect such as LiNbO 3 is preferably used.
- the phase modulator 10 may use a phase modulation effect in EA (Electro-Absorption), SOA (Semiconductor Optical Amplifier), or the like.
- EA Electro-Absorption
- SOA semiconductor Optical Amplifier
- Many phase modulators 10 generally have polarization dependence, but it is desirable to achieve non-polarization by using a non-polarized waveform optical device or a method based on polarization diversity.
- the driving frequency of the phase modulator 10 is the transmission speed of the pulse transmission.
- the electric amplifier 8 outputs a drive signal for driving the phase modulator 10 by the output of the phase shifter 7.
- the second-order dispersion element 11 is, for example, a single-mode optical fiber having a group velocity dispersion characteristic in which a zero-dispersion region exists near a 1.3-m wavelength band, a diffraction grating pair, or a fiber Bragg.
- Gratings, VIPA-type tunable dispersion compensators, arrayed waveguide gratings, and combinations of gratings and spatial modulators can be used.
- optical electric field e (z, t) in a dispersive medium such as an optical fiber / complex is expressed by the Max ⁇ I equation d 2 e ⁇ 2 d 2 e
- Equation (12) the envelope shape of the spectrum U ( ⁇ ) at the receiving end ⁇ (Fig. 3 (b)) Signal U (0, Equal to the envelope shape of (0)) (Fig. 3 ( 3 )). That is, from equations (12) and (15), v (t) is finally expressed as equation (17) using the input signal spectrum U in to the optical fiber transmission line 2.
- v (t) (t ID ) exp (- iKt 2/2 + ( ⁇ I ⁇ )) ⁇ ) (17)
- the shape of the input spectrum U in (w) can be reproduced to the output by v (t) .
- the Fourier transform image of the optical pulse can be generated by the combination of the c- phase modulator 10 and the secondary dispersion element 11.
- FIG. 5 is a diagram showing waveform distortion of an optical pulse and the effect of compensation.
- This figure shows the result of performing a numerical calculation using the experimental parameters of Non-Patent Document 4 in order to confirm the effect of dispersion compensation in the Fourier optical transmission system of the present embodiment.
- circles, dashed lines, and solid lines indicate the time of the optical signal at points A, B, and C in FIG. 1 (that is, before and after transmission of the optical fiber transmission line 2 and at the output of the optical Fourier transformer 3).
- the waveform is shown.
