In High Performance Telecom components, we focus on 10 to 100 Gbit transmission and detection optochips and OEICs. In this performance range, high quality and performance optochips are a key enabler for cost efficient optical component and modules, and thus a key success factor for our customers.
The 1.2-1.9 µm wavelength range is very interesting for sensing applications. Here, telecom technology based lasers and detectors are in our portfolio serving applications from industrial combustion sensing to satellite-to-satellite optical communication.
Terahertz waves carry with them a multitude of potential applications, ranging from detection of ill teeth over final product control in drug manufacturing, up to detection of hazardous substances. HHI targets here to use telecom technology to make terahertz generation and detection a handheld technology.
Within the Fraunhofer mission "to undertake applied research of direct utility to private and public enterprise and of wide benefit to society" , we offer production and development services in all our activities to the German and international industry. As an example, if you already have a concrete optochip design in mind, we offer additional consulting and would do design and fabrication iterations. Or if you start with a target spec, we would typically begin with a feasibility study and generate a design of our own. In all cases, we are able and willing to do initial production volumes in ISO certified, qualified production. Besides optochip design, we also offer our e-beam services, and design-to-spec diffractive optical elements.

Detectors and Photoreceivers
The detector group develops and manufactures high-speed photodetectors and photoreceivers as optoelectronic integrated circuits (OEICs) based on InP according to customer specifications, preferably for the 1.3 - 1.55 µm wavelength region with 1-150 GHz speed of operation.
InP based Mach-Zehnder Modulators
The modulator group is developing InP based Modulators with a travelling wave electrode design.
Lasers
Laser diodes are being developed for a variety of applications in the area of optical tele- and data communications, and sensors.
Polymer OEIC
The polymers technology group develops and manufactures polymers photonic components such as planar light wave circuits (PLC) or optoelectronic integrated circuits (OEICs) according to customer specifications.
Terahertz generation and detection
HHI applies its telecom matured InP-technology for developing photomixers and photoconductive antennas which convert optical signals in the 1.5 µm wavelength range into THz radiation and vice versa.
Diffractive optical elements
Our portfolio of elements, mainly implemented in quartz glass, silica and silicon, covers the wavelength range from the DUV to the IR region.
Technology: III/V Epitaxy
The Epitaxy group at HHI manufactures and develops InP-based wafers for optical and opto-electronic components.
Technology: Processing
At HHI we have industry standard cleanroom facilities of ISO classes 4 to 6 (former classes 10 to 1000). Our complete process line starts with ebeam lithography for mask fabrication and direct writing and includes all technology steps up to final electroplating and AuSn-sputtering for contact-pads or flip-chip-bumps.
Qualification support
For Telecom application, Telcordia Qualification is a must for all components targeting real applications. We have most capabilites in house to perform Telcordia tests.
