摘要： An angle modulating portion 1 converts an inputted electrical signal into a predetermined angle-modulated signal. An optical modulating portion 2 converts the angle-modulated signal outputted from the angle modulating portion 1 into an optical-modulated signal and sends the optical-modulated signal to an optical waveguide portion 3. An interference portion 6 separates the optical-modulated signal transmitted through the optical waveguide portion 3 into two optical signals having predetermined difference in propagation delay and then combines the optical signals. An optical/electrical converting portion 4 subjects the combined optical signal to homodyne detection, to acquire a demodulated signal of the original electrical signal and output the electrical signal. That is, the interference portion 6 and the optical/electrical converting portion 4 constitute a delayed detection system of an optical signal, so that the delayed detection system performs conversion processing of an optical signal into an electrical signal and angle demodulation processing simultaneously. In this way, a signal with a wide-band and a high-frequency can be acquired by demodulation without electrical part for wide-bands and high-frequencies.

摘要： The effective rate of deactivation from the terminal state (110) to the ground state (107) of a rare earth ion doped optical material in a four-level amplifying or lasing scheme may be increased greatly by doping the optical material with two rare earth ions, an activator (101) (chosen among Tru ion, Pr ion, ND ion; Er ion) and a deactivator (102) (chosen among Eu ion, Sm ion, Tb ion). Energy transfer occurs between the terminal state in the activator ion and the deactivator ion. The transition from the deactivator to the ground state occurs via phonon emission. By increasing the deactivation rate, the efficiency of the laser and the amplifier is increased.

摘要： A core of a fluorozirconate optical fiber is doped with rare earth ions, namely trivalent Dy ions. The Dy ion makes an absorption transition with excitation light generated by an 800 nm semiconductor laser module. Then the Dy ion undergoes transitions, namely a nonradiative transition involving phonon emission, a transition to a metastable excited level, and a radiative transition wherein radiation corresponding to the 1.28 µm to 1.35 µmrange occurs, thereafter returning to its ground state level. The Dy ion having an electrovalence of three can be pumped with a high-output 800 nm semiconductor laser module and is not subject to saturation at a lower energy level of population inversion. Using an optical fiber of the invention, a higher gain is obtained in the region of 1.3 µm telecommunications window.
