Abstract: Optical systems can emit train(s) of light pulses onto objects to derive a distance between the light source and the object. Achieving meter or centimeter resolution may require very short light pulses. It is not trivial to design a circuit that can generate narrow current pulses for driving a diode that emits the light pulses. An improved driver circuit has a pre-charge path comprising one or more inductive elements and a fire path comprising the diode. Switches in the driver circuit are controlled with predefined states during different intervals to pre-charge current in the one or more inductive elements prior to flowing current through the fire path to pulse the diode.

Abstract: A system and method for engineering loss in a physical system by steering parameters of the physical system to the vicinity of an exceptional point is disclosed. In the vicinity of an exceptional point, localization of the fields helps to enhance any linear or nonlinear processes. As examples loss-induced transparency in the intracavity field intensities of coupled resonators, loss-induced suppression and enhancement of thermal nonlinearity in coupled resonators and loss-induced suppression and revival of Raman lasing in whispering-gallery-microcavities are demonstrated.

Abstract: A wafer is formed with a plurality of division lines on a front surface of a single crystal substrate having an off angle and formed with devices in a plurality of regions partitioned by the division lines. The wafer is processed by setting a numerical aperture (NA) of a focusing lens for focusing a pulsed laser beam so that a value obtained by dividing the numerical aperture (NA) by a refractive index (N) of the single crystal substrate falls within the range from 0.05 to 0.2. The pulsed laser beam is applied along the division lines, with a focal point of the pulsed laser beam positioned at a desired position from a back surface of the single crystal substrate, so as to form shield tunnels each composed of a pore and a pore-shielding amorphous portion along the division lines from the focal point positioned inside the single crystal substrate.

Abstract: A generation unit generates adjustment information to adjust a first clock indicating a timing of illumination of a laser beam to scan on a screen, based on a scanning position to be scanned by the laser beam.On the basis of the adjustment information, adjustment unit adjusts the first clock to a second clock different from the first clock. Then, in synchronization with the second clock, the laser beam is allowed to illuminate as a pixel. This may be applicable to a projection apparatus for projecting an image on the screen, for example.
