Apparatus for Generating Random Numbers using an Optical Parametric Oscillator

Ref.-Nr.: 1201-5494-BC

Sensoren, Geräte und Komponenten
Photonics

The invention relates to an apparatus for generating random numbers, using an optical parametric oscillator.

The generation of random numbers is important in information science as well as in modelling and simulation. In cryptography, for instance, random numbers are needed for encryption algorithms. Preferably, the generated numbers are true (i.e. non-predictable) and have an equal distribution.

The apparatus according to the invention is based on the bi-stable outcome of an optical ...

METHOD FOR PRODUCING RANDOM NUMBERS ON THE BASIS OF QUANTUM NOISE

Ref.-Nr.: 1629-5565-WT

Sensoren, Geräte und Komponenten
Photonics

The invention relates to a new method for an improved production of random numbers and verification of their randomness. In order to do so, it uses the quantum mechanical properties of microscopic particles and structures. A number sequence is generated by means of a repetitive quantum mechanical random process. The measurement of this process is performed by a homodyndetection of an optical input signal, where the signal interferes with a local oscillator, e.g. a laser, at a central beam splitter ...

Near-Unity Efficiency: Novel Light Collecting Antenna for Quantum Technologies

Ref.-Nr.: 1629-6049-WT

Photonics

The invention relates to a new concept for a high efficiency light antenna, namely the Truncated Omnidirectional Reflector (TOR). It is well suited for obtaining directional emission and efficient fiber coupling from various types of light sources like single photon emitters.
Especially in the fast-growing field of quantum technologies efficient collectors for solid-state single photon emitters are needed. Achieving collector efficiencies of more than 95% into the fundamental Gaussian mode, ...

Precise LIDAR Devices: Metasurface for Large-Angle Beam Steering

Ref.-Nr.: 1201-6235-BC

Photonics

The invention relates to a new device for precise large-angle beam steering at an extended wavelength range. It is based on an electrically-controlled metasurface and allows for the implementation in advanced LIDAR systems.

Metasurfaces are used to change properties of light and can therefore be used to steer an incoming beam. However, common devices are lacking spatial resolution and are thus limited to small angles. Furthermore, state-of-the-art metasurfaces for respective applications ...

Towards New Optical Devices: The Electrically-Controlled Dynamic Metasurface

Ref.-Nr.: 1201-5777-BC

Photonics

The invention relates to a new dynamic optical component based on a metasurface that can be operated electrically at visible frequencies. Realizing pixel level addressability of the metasurface properties paves the way towards the next generation of optical devices for data storage and communication.

Nanoantennas on a metasurface are used to directly change properties of light but are typically limited to static effects. However, state-of-the-art devices with optical reconfigurability are ...
