Quantum Key Distribution only supports low-key rates, so only small data rates are possible using one-time pad encryption. Quantum Key Distribution can be combined with a classical algorithm, such as an Advanced Encryption Standard (AES) to solve this limitation. European Space...
In space-based relay quantum communication, the satellite is the trusted actor in charge of distributing the keys and being quantum; it has a higher degree of security since it can be verified if they are secret. Therefore, for this system, it is necessary to have a trusted...
Optical transceivers employ fiber optic technology to convert electrical signals into light signals. Doing so can transmit the information in the optical fiber, traveling at very high speeds and long distances. A transceiver includes two parts: a transmitter, and a receiver...
Optical transceiver is currently being used in communications satellites. On September 8, 2022, the first commercial satellite using optical interconnects was launched, called Eutelsat KONNECT VHTS, which hosts Thales Alenia Space DTP5G OBP, a processor with digital optical...
Reaching the TRL 9 scale has encouraged designers to use this technology as a solution in their systems and thus improve them to manufacture satellites with enhanced characteristics that support the requirements of today’s world.
Optocap have experience in the assembly and packaging of a wide range of Photonic Integrated Circuit (PIC) devices including Silicon PIC and InP PIC devices. A PIC is a photonic integrated circuit that integrates multiple photonic functions, such as lasers, detectors, modulators...
A key function of an optoelectronic device is to manipulate light. As a result the packaging and assembly processes for many optoelectronic components can be significantly more complex than traditional microelectronic devices.
Our capabilities range from the simple selection of a ball lens for coupling the output of an optical fibre into a photodiode, to providing a much wider module design service. This may include proof-of-concept design evaluation, opto-mechanical and thermal tolerancing leading to...
Surface contamination involving micrometric particles, microbiological agents, molecular adsorbate and others, represent a significant hazard in many areas of industry. For instance, a high level cleanliness is a critical requirement that any EEE device has to fulfil at any...
Passive liquid crystal (LC) devices are becoming an interesting alternative for the manufacturing of photonic devices in spatial applications. These devices feature a number of advantages in this environment, the lack of movable parts, and of exposed electronics being among the...
