Fraunhofer HHI at Photonics West 2016, February 13-18 in San Francisco

You find the following highlights at our boot 4629-28, hall D:

Terahertz sensing – World’s most compact THz-transceiver

Terahertz radiation has proven potential as versatile tool for non-destructive testing (NDT). Up to now, the application of THz technologies in industrial environments is severely impeded due to the complexity of today’s THz sensor heads. Especially reflection measurements suffer from bulky and expensive devices. The Fraunhofer HHI presents a novel integrated THz-transceiver, which combines emitter and detector in a single, compact module and allows for measurements under normal incidence for the first time.

Fiber optical 3D shape sensors: Cyberglove – control of robots with nerves out of glass

A new concept for a multifunctional fiber sensor platform for 3D shape sensing is developed by applying a novel femtosecond laser processing technology for high-precision direct writing of Bragg gratings within the core and the cladding of optical fibers. These sensors are exemplary integrated in a Cyberglove, where the movements of each individual finger can be detected, visualized, and simultaneously transferred to a robotic hand.

Integrated Tunable Lasers for THz generation: Dual tunable laser chip at 1.5µm – based on Fraunhofer HHI´s hybrid integration platform PolyBoard

Fraunhofer HHI´s PolyBoard platform enables the hybrid integration in one chip of two Polymer/InP DBR tunable lasers in the 1.5 µm wavelength range. Each laser shows a tuning range of 20 nm (2.4 THz), and continuous sweeps of more than 9 nm (1.1 THz) have been demonstrated. Application fields of such dual optical sources are DWDM optical networks, CW Terahertz systems, microwave photonics, and spectroscopy.
