Abstract: An apparatus comprising a visible light source(s), multimode optical fiber(s), light coupler(s), an optional spatial light modulator(s), and an optional projection lens(es). The light source has a 1/e half-width emission bandwidth. The light coupler couples the light source to the multimode optical fiber(s) such that objective speckle contrast is reduced. The multimode optical fiber(s) may pass light from the coupler to an optional spatial light modulator. The spatial light modulator may modulate the light to form an image. The projection lens may transfer light onto an image plane or to illuminate objects. The objective speckle contrast at the end of the multimode fiber in combination with the projection lens diameter (if employed) and wavelength diversity may result in viewed images at the viewer's eye, or other detector, exhibiting speckle contrast that may be 1% or less.

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: 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 set mode is generated at the multi-mode interference portion in a 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.
