  • Publication number: 20220209494
    Abstract: A driver circuit may include a source, a first circuit path, and a second circuit path. The a first circuit path may be connected to the source and include a first anode pad, a first set of connecting elements to connect the first anode pad to an anode of an optical load, a second anode pad that is separate from the first anode pad, a second set of connecting elements to connect the anode of the optical load to the second anode pad, and a switch. The switch being in a closed state causes current to charge the first set of connecting elements and the second set of connecting elements through the first circuit path. The switch transitioning from the closed state to the open state causes the first set of connecting elements to discharge current through the second circuit path to provide an electrical pulse to the optical load.

  • Publication number: 20220011410
    Abstract: In some implementations, an electrical drive circuit may generate a rectangular optical pulse using cathode pre-charge and cathode-pull compensation. The electrical drive circuit may include an anode and a cathode to connect an optical load, a switch, a first source connected between the anode and a ground, a rectifier connected between the cathode and the switch, a capacitor connected in parallel with the rectifier, a second source connected to the ground, and an inductor connected between the switch and the second source. In some implementations, when the switch is closed and the optical load is connected, a first current is provided to the optical load through the first source, the rectifier, and the switch, and a second current is provided to the optical load through the first source, the capacitor, and the switch, where a rise time of the first current complements a fall time of the second current.

  • Publication number: 20210296855
    Abstract: An electrical drive circuit may charge one or more inductive elements, where the electrical drive circuit includes the one or more inductive elements and a capacitive element in series between the one or more inductive elements and the optical load, and where the electrical drive circuit is connected to one or more sources. The electrical drive circuit may generate, after the charging and for a first time interval, a main electrical pulse. The electrical drive circuit may discharge, after the charging and for a second time interval, the one or more inductive elements to provide a compensation electrical pulse, where at least a portion of the second time interval overlaps with the first time interval. The electrical drive circuit may combine the main electrical pulse and the compensation electrical pulse into a combined electrical pulse. The electrical drive circuit may provide the combined electrical pulse to the optical load.

  • Publication number: 20210296857
    Abstract: An optical device may drive a compensation section of a multi-section optical load to emit a compensation optical pulse by providing, for a first time interval, a compensation electrical pulse to the compensation section. The optical device may drive a main section of the multi-section optical load to emit a main optical pulse by generating, for a second time interval, a main electrical pulse, wherein at least a portion of the first time interval overlaps with the second time interval. The optical device may emit a combined optical pulse, wherein the combined optical pulse includes the compensation optical pulse and the main optical pulse, and wherein the combined optical pulse has a shorter rise time than the main optical pulse.

  • Publication number: 20200333438
    Abstract: A driver circuit, for generating narrow electrical pulses of high repetition rate with high peak current and low after pulse ringing to drive an optical load, may include a source, a first circuit path, and a second circuit path. The first circuit path may be connected to the source and may include inductive elements and a switch. The switch being in a closed state may charge current in the inductive elements through the first circuit path. The second circuit path may connect to the optical load and may be connected to the source. The second circuit path may include the inductive elements and a capacitive element in series with the optical load. The switch transitioning from the closed state to an open state may discharge current from the inductive elements through the second circuit path to provide an electrical pulse to the optical load.
