A system for detecting objects, for driver assistance equipment in motor vehicles for example, includes a transmitter for transmitting towards an object an optical signal having a signal energy. The optical signal transmitted includes at least one encoded pulse sequence with the signal energy distributed over the pulse sequence. A receiver receives an echo signal resulting from reflection of the optical signal at the object with the time delay of the echo signal is indicative of the distance to the object.

Method of detecting objects, corresponding system and apparatus

An optoelectronic device may include a package having a component for sending/receiving optical signals along a first direction, and a chip of semiconductor material housed within the package. The chip may have a main surface and a portion exposed on the main surface for sending/receiving the optical signals along a second direction different from the first direction. The optoelectronic device may further include a component for deflecting the optical signals between the first direction and the second direction, the component being mounted on the main surface.

Optoelectronic device having improved optical coupling

An intra-board chip-to-chip optical communications system has a high bit rate and high data throughput based on the use of a silicon photonic interposer. The system includes a multi-substrate electro-optical structure for communications with CMOS and/or BiCMOS IC chips of a PCB. The structure includes a multi-chip module primary substrate mounted over the supporting PCB. The multi-chip module primary substrate implements high frequency electrical interconnections between transceiver circuit chips, mounted on the silicon photonic interposer, and the IC chips.

Multi-substrate electro-optical interconnection system

An optical cross-connect for the switching of optical channels at variable bit-rate (up to 10 Gbit/s), wavelength division multiplexed on bi-directional optical fibers forming the transmission backbone of a transport network; in particular the cross-connect can be interfaced to fibers crossing the nodes of a ring having large territorial extension, provided with protection fibers. The cross-connect includes a spatial Split & Select input stage of WDM aggregates, followed by a set of channel filters tunable on the whole optical range occupied by the channels, which jointly form a structure strictly not blocking the access to the channels by a set of bridge units whose functionality is selectable on a per-channel basis, such as for instance: transit, drop/insert, regeneration, etc. An output optical spatial Split & Select stage connects in a strictly non-blocking way the single channels from bridge units to optical multiplexers that reconstruct the WDM aggregate on the output fibers. The duplicated architecture of the bridge units for the protection fibers enables the protection of each single local drop/insert channel (FIGS. and ).
