It further comprises a coupling tube (24) surrounding facing ends of the first portion (9a) and the second portion (9b), said coupling tube (24) being adjusted in size to fit in between said first and second ring bulges (22, 23), and a coupling and protecting sheath (25) enclosing said first ring bulge (22), coupling tube (24) and second ring bulge (23) in a watertight manner.

Monolithically integrated electro-absorption modulated lasers (EMLs) and methods of manufacture are disclosed. A vertical stacked waveguide vertical integration for a distributed feedback (DFB) laser, an electro-absorption modulator (EAM), and a passive output waveguide, the DFB laser, the EAM, and the output waveguide being optically coupled using a lateral tapered vertical optical coupler. Vertical integration using transverse tapered vertical optical couplers provides an alternative for traditional docking coupling of lasers and EAMs, which is possible to improve reliability of high power operation with extended lifetime. Optionally, the EML includes monolithic integrated electronic circuitry, such as drive and control electronics of the DFB laser and EAM. Advantageously, the integrated EAM drive and control circuit includes a high speed electro-optic control loop for very high speed linearization and temperature compensation, e.g., enabling advanced modulation schemes, such as PAM-4 and DP-QPSK, for analog optical data center interconnect applications. Some embodiments are compatible with fabrication using a single epitaxial growth.

An compact instrumented downhole coupling that includes a carrier and a set of sensors and electronics that are installed within the carrier. The carrier is a tubular structure having couplings at each end and a bore extending through the carrier from the first end to the second end, forming a carrier wall between the bore and the exterior surface of the carrier. The bore and couplings are offset from a central axis of the carrier (the axis of the cylindrical outer surface of the carrier), resulting in a thicker portion of the carrier wall on one side of the carrier. Cavities are formed (e.g., by drilling holes) within the thicker portion of the carrier wall. One or more sensors and corresponding electronics are then positioned within the cavities, so that the carrier wall itself forms a housing for the sensors and electronics.

Provided is a plug connection which ensures signal integrity, in particular at high data rates and with a large number of plug-in cycles, in a cost-effective manner. A dielectric is in each case arranged between the pin contacts of a connector and the socket contacts of a mating connector to ensure galvanic isolation and capacitive connection between them. In this way the connected circuit electronics can be simplified. There is no need for a coupling capacitor and impedance matching can be performed the geometric arrangement of the contacts. In particular, it ensures that there is a variety of different plug connections to choose from with different properties, in particular with different impedances and capacitances.
