Quantum race will be long: Peter Leibinger in Munich

Dr Peter Leibinger, CTO of Trumpf, has called for a joined-up strategy on quantum technologies on the first day of Laser World of Photonics in Munich

Lasers for Quantum Applications and Biotechnology from Toptica

will display their latest laser systems for scientific and industrial applications at Photonics West, booth #1227. The company is presenting several products at this year’s live event including lasers for quantum applications and biotechnology. Live demos can be found at their booth during the exhibition.

Efficiency ranging from deep UV to near-infrared

Nanoscribe launches Quantum X align

Nanoscribe, is debuting the Quantum X align, a new high-performance 3D printer at the Photonics West Conference and Exhibition. The Quantum X align is the first 3D printer with 3D alignment capabilities that enables the printing of freeform microoptical elements directly onto optical fibres and photonic chips, as the company aims to set new standards in the design and fabrication of microoptical elements.

Aurea Technology showcases optical building blocks for quantum technologies

Aurea Technology is exhibiting advanced optical building blocks required in Quantum technologies at the SPIE Photonics West.

With more than 10 years of experience in quantum optics, Aurea Technology offers a complete suite of high-performance optical modules and instruments for Quantum Communications, Quantum-safe Security, and Quantum Sensing. The fully comprehensive suite of the high-performance optical building blocks from Aurea Technology includes:

Figure 1: Light propagation inside a photonic crystal is forbidden by a propagation gap, hence common plane waves are reflected and hardly penetrate into the crystal. By shaping the incident waves, they can be steered deep into the crystal. (Image: COPS, University of Twente) 

Crossing the forbidden gap

A team of researchers has achieved a new level of control over light entering photonic crystals
