Title: Broadband optical frequency modulator
Inventor: KOBAYASHI NORIFUMI
IPC: H04B10/61
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To expand frequency deviation width by propagating a multiple optical signal and generating nonlinear effects. SOLUTION: An optical frequency modulation light source 1 outputs an optical signal of a central optical frequency A. A local oscillation light source 2 outputs a single optical signal of a central optical frequency B. After an optical amplifier 4 amplifies an optical signal that multiplexes an optical signal S (a) of the frequency A and an optical signal S (b) of the frequency B, the optical signal is inputted to an optical fiber 5. Then, a new optical signal S (2a-b) is generated in an optical frequency 2A-B by a tertiary nonlinear effect of a quartz optical fiber.  In an optical frequency modulation component in the optical signal S (2a-b), similarly with an expression representing its generation frequency, i.e., '2A-B', a modulation component of the signal S (a) is doubled, the phase of a modulation component of the S (b) is inverted and these two modulation components are added and appear. That is, by making local oscillation light S (b) non modulation, the frequency modulation component of the signal S (2a-b) will have frequency deviation width that doubles the S (a).

Filed: 1984-08-31
Abstract: PURPOSE:To prevent a signal spectrum distribution from being disturbed by harmonics existing in parasitic with a system by selecting a reference frequency of the signal so as to avoid harmonics of a system frequency and a biased frequency. CONSTITUTION:A signal from a high voltage distribution line 1 of each system is detected by a transmission current detecting circuit 41 via a current transformer 2. The spectrum analysis of harmonics and a noise frequency near the signal frequency is executed at the non-transmission state of the signal, the stray state is supervised and the result of supervision is given to a transmission control circuit 42. When it is required to transmit measured information or the like, the control circuit 42 transmits the result of supervision to the reception side. The reception side compares the result of supervision detected at the own side with the result of supervision transmitted, and when there is no difference, a harmonic level is decided and transmitted to the transmission side. Thus, the control circuit 42 uses the harmonic level to transmit the normal measuring and supervisory information to the reception side.
