The Fraunhofer Heinrich Hertz Institute HHI presents the latest developments in sensory and laser technology at the Photonics West. Meet our experts at the joint German booth 4629-28, hall D on February 13-18 in San Francisco, United States.
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.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
