摘要： A pulse generator circuit (20a) configured to apply a current pulse to two output terminals (204, 206) . The pulse generator circuit (20a) comprises an LC resonant circuit (Lr, Cr) comprising an inductance (Lr) and a capacitance (Cr) connected in series between a first node (210) and a negative input terminal (202). The pulse generator circuit (20a) comprises moreover a charge circuit (220) configured to charge the capacitance (Cr) via a supply voltage ( Vcc ), a first electronic switch (S1) configured to selectively short-circuit the two output terminals (204, 206), a second electronic switch (S2) configured to selectively connect the two output terminals (204, 206) in parallel with the LC resonant circuit (Lr, Cr) and a control circuit (208a) configured to drive the first (S1) and the second (S2) electronic switch. Specifically, the control circuit (208a) repeats the following steps during each switching cycle:
- for a first time-interval ( T 1 ) close the first electronic switch (S1) and open the second electronic switch (S2), wherein the capacitance (Cr) is charged via the charge circuit (220);
- for a following second time-interval ( T 2 ) close both the first (S1) and the second (S2) electronic switch, wherein the LC resonant circuit (Lr, Cr) oscillates with a given resonant period (Tr);
- for a following third time-interval ( T 3 , T ON ) open the first electronic switch (S1) and close the second electronic switch (S2), wherein the LC resonant circuit (Lr, Cr) provides a current ( i cr ) to the two output terminals (204, 206); and
- for a following fourth time-interval ( T 2 ) close both the first (S1) and the second (S2) electronic switch, wherein the LC resonant circuit (Lr, Cr) oscillates with the given resonant period (Tr).

摘要： An OMA controller circuit utilizes a first ADC with an input coupled for receiving a residual error signal indicating a difference between a monitoring signal and a target data signal. A second ADC has an input coupled for receiving the target data signal. A first digital filter has an input coupled to an output of the first ADC, and a second digital filter has an input coupled to an output of the second ADC. A digital multiplier has a first input coupled to an output of the first digital filter and a second input coupled to an output of the second digital filter. An integrator has an input coupled to an output of the digital multiplier and an output providing an average error signal with sign and magnitude. The digital multiplier uses a four quadrant multiplier to perform a cross-correlation on the residual error and the target data signal.

摘要： Es wird eine Laserlichtquelle zur Abstrahlung von kohärenter elektromagnetischer Strahlung (10) mit einem vertikalen Fernfeldstrahlprofil (121) angegeben mit einer Halbleiterschichtenfolge (1) zur Erzeugung der kohärenten elektromagnetischen Strahlung mit einem aktiven Bereich (3) auf einem Substrat (2), wobei die kohärente elektromagnetische Strahlung im Betrieb mindestens von einem Hauptemissionsbereich (5) einer Strahlungsauskoppelfläche (4) mit einer Abstrahlrichtung (11) abgestrahlt wird und die Strahlungsauskoppelfläche (4) durch eine Seitenfläche der Halbleiterschichtenfolge (1) gebildet ist, und einem Filterelement (13), das im Betrieb erzeugte kohärente elektromagnetische Strahlung (12), die von einem zum Hauptemissionsbereich (5) vertikal versetzten und räumlich getrennten Nebenemissionsbereich (6) der Strahlungsauskoppelfläche (4) abgestrahlt wird, im vertikalen Fernfeldstrahlprofil (121) unterdrückt.
