    Abstract: An arrangement for the resonant frequency doubling of multimode laser radiation with resonators is provided, including mirrors and an optically nonlinear material. The arrangement ensures a dispersion-free tuning of the length of a passive resonator, and enables the frequency doubling of a multimode laser, which is resonant simultaneously for all modes of the laser radiation, and which is achieved by pairs of mutually oppositely disposed movable elements of an optically transparent material, such as prisms (P1, P2). The prisms are brought into the beam path of the resonator (R), formed from mirrors (M1 to M4) and optically nonlinear material (BBO). The prisms are movable elements (P1, P2) which are connected to adjusting elements such as piezoactuators, so that the optical length of the resonator (R) can be tuned and compensation for dispersion attained.

    Abstract: A thermo-optic wave-guide switch. The switch selectively switches the paths of an optical signal. The thermo-optic wave-guide switch includes a multi-mode wave-guide having an input port, a first output port and a second output port, and a thin film heater formed on the side of the multi-mode wave-guide. When the thin film heater does not provide the multi-mode wave-guide with heat and a signal is received by the input port, the first output port outputs the signal in a cross state according to the self-image theorem, and when the thin film heater provides the multi-mode wave-guide with heat and a signal is received by the input port, the second output port outputs the signal in a bar state.

    Abstract: A set−reset flip−flop of all−optical operation. A set light is inputted through a set port. Then, a multimode interference portion in a waveguide oscillates only in a set mode. As a result, a noninverted output Q is produced from a noninverted output port. Even if the input of the set light is turned off, the output state is maintained. When a reset light is inputted through a reset port, the multimode interference portion stops its oscillation in the set mode and causes oscillation in a reset mode. Thus, an inverted output Q−bar is generated from an inverted output port. Even if the reset light input is turned off, the output state is maintained.
