Abstract: A laser parametric generator for surgical applications is disclosed which utilizes short-pulse, mid-infrared radiation. The mid-infrared radiation may be produced by a pump laser source (20), such as a neodymium-doped laser, which is parametrically downconverted in a suitable nonlinear crystal (15) to the desired mid-infrared range. The short pulses reduce unwanted thermal effects and changes in adjacent to potentially submicron levels. The parametrically converted radiation source preferably produces pulse durations shorter than 25 ns at or near 3.0 νm but preferably close to the water absorption maximum associated with the tissue. The down-conversion to the desired mid-infrared wavelength is preferably produced by a nonlinear crystal (15) such as KTP or its isomorphs. In one embodiment, a non-critically phased-matched crystal is utilized to shift the wavelength from a near-infrared laser source emitting at or around 880 to 900 nm to the desired 2.9 to 3.0 νm wavelength range. A fiber, fiber bundle or another waveguide means utilized to separate the pump laser from the optical parametric oscillation (OPO) cavity is also included as part of the invention.

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.

Abstract: The present invention provides a set-reset flip-flop operating in an all-optical manner. In this invention, a set pulse is inputted from the setting port. In doing so, only oscillation in setting mode is generated at the multi-mode interference portion in waveguide. As a result, a non-inverting output Q is obtained from the non-inverting output port. This state is then continued even if the set pulse input goes off. Next, a reset pulse is inputted to the resetting port. In doing so, at the multi-mode interference portion, oscillation of light in the set mode is halted, and oscillation in the reset mode occurs. As a result, it is possible to obtain an inverting output Q-bar from the inverting output port. This state is then continued even if the reset pulse goes off.

Abstract: PURPOSE: An externally controllable waveguide type higher order mode generator is provided, which has a simple structure using a straight waveguide and a straight electrode, and thus simplifies a structure of an optoelectronic device and its driving method. CONSTITUTION: The higher order mode generator comprises a straight waveguide comprising a top and a bottom clad layer(2,3) and a core layer(1) supporting higher order mode above 1st order mode, and a straight electrode(4) crossing the straight waveguide obliquely as having an angle alpha with the straight waveguide. If a propagation angle of mth order mode is theta m to couple 0th order waveguide mode to mth order waveguide mode, the angle of the electrode alpha and the propagation angle theta m of the higher order mode satisfies that alpha is larger than a half of the theta m.
