Title: Optical waveguide device
Inventor: FUKUDA YOSHIAKI
IPC: G02B6/12
Filed: 1983-12-26
Abstract: PURPOSE:To suppress optical damage by providing a means, which irradiates uniformly the light having a specific wavelength or shorter to the surface of a thin film optical waveguide, not to give a thermal disturbance to peripheral devices. CONSTITUTION:An input luminous flux 5 is introduced into an optical waveguide 2 by a prism 3 and is propagated in the optical waveguide 2 and is led out to the external by a prism 4. A mercury-arc lamp 9 is provided above the optical waveguide 2, and light 10 having <=400nm wavelength is irradiated unformly to the surface of the optical waveguide 2. In this constitution, intensities of output luminous fluxes 7 and 8 are reduced by optical damage similarly to conventional constitution when the light 10 is not irradiated; but when the light 10 is irradiated, electrons which are excited from the impurity level by guided luminous flux 6 and are captured in a tarp can escape from the trap by the energy of the light 10. Free electrons are coupled with nearby holes quickly again to prevent occurrence of polarization. Since it is considered that the time spent in recoupling between electrons and holes is sufficiently short, optical damage of the optical waveguide 2 is suppressed practically as the result.

Title: Frequency controller
Inventor: SUZUKI FUMIAKI
IPC: H04B7/15
Filed: 1983-12-28
Abstract: PURPOSE:To prevent line interruption due to frequency control even when an oscillator whose frequency is changed stepwise as a local oscillator by changing an output frequency of the local oscillator only when no input signal exists and not changing it when the input signal exists. CONSTITUTION:A modulator 101 modulates an output 7 of the local oscillator 103 by using an input signal 1 and outputs a modulation signal 2. A signal interuptor 102 transmits a modulation signal 2 only when the input signal 1 exists by using a signal interruption signal 3 inputted separately. On the other hand, an oscillator control circuit 105 outputs an oscillator control signal 6 in response to the frequency error signal inputted separately when no input signal 1 exists with the signal interruption signal 3 and controls the local oscillator 103 so that the frequency error at the reception side is eliminated. Then when the input signal 1 exists, the oscillator control signal 6 is outputted by using the frequency error signal 5 just before the signal interruption signal 3 is changed from ''interruption'' to ''connection'', and holds the value until the signal interruption signal 3 becomes ''interruption''.
