    Abstract: An optoelectronic device has a first component provided to generate radiation, a second component provided to receive radiation, a connection board and a frame. The first component and the second component are arranged on the connection board. The frame is arranged on the connection board. The first component is arranged in a first opening in the frame. The second component is arranged in a second opening in the frame. The first opening and the second opening extend from a main face of the frame opposite the connection board in the direction of the connection board. The main face between the first opening and the second opening has an intermediate region, in which a reflection of radiation incident on the main face is reduced.

    Abstract: A PWM controlled current source includes a selection input, a modulation input, a switchable current source which can be switched by means of a signal at a control terminal and whose current output is configured for connection to a load, and an inverter circuit including an input node and an output coupled to the control terminal. The inverter circuit has a capacitance conditioned by elements of the inverter circuit. A start signal can be supplied to the input node in dependence on a selection signal at the selection input, which controls the switchable current source via the inverter circuit. The PWM controlled current source also includes a voltage-to-current converter that generates a current derived from a modulation signal at the modulation input and supplies it to the input node. The supplied current disconnects the switchable current source after a time period predetermined by the conditioned capacitance.
