Abstract: An optoelectronic assembly includes a printed circuit board (PCB), an integrated circuit (IC) substrate operably mounted on the PCB, the IC substrate comprising at least one of active elements and passive elements, a vertical-cavity surface-emitting laser (VCSEL) operably mounted on a first surface of the IC substrate, an optical detector operably mounted adjacent to the VCSEL on the first surface of the IC substrate, and a molding compound formed on the IC substrate encapsulating a plurality of sides of the VCSEL and a plurality of sides of the optical detector, in which at least one electrical communication path between the optical detector and the VCSEL is confined within the IC substrate.

Abstract: An optical driver circuit is described herein having a plurality of drive cells and delay segments between their control signals resulting in the control of the rising and falling edge rates for an optical device driven by the optical driver circuit.

Abstract: A layered pulse generator for a vertical-cavity surface-emitting laser (“VCSEL”) driver is disclosed consisting of three elements: a low-speed pulse generator, a high-speed pulse generator, and a pulse generator selector, all of which are on-chip with the VCSEL driver. By providing these elements on-chip, overall system power and complexity are reduced while allowing for significantly higher pulse train frequencies compared with known systems. The high-speed pulse generator is capable of generating pulses faster and with higher resolution than that of the low-speed pulse generator. The high-speed pulse generator uses multiple clock outputs, phase shifted, and synthesized into a single pulse waveform capable of wide-ranging frequencies, duty cycles and pulse counts.
