Freedom Photonics has demonstrated a semiconductor modulator with 1.2V static Vπ and >20 GHz bandwidth, and photodetectors that operate linearly up to 100mA photocurrent and with a bandwidth exceeding 20 GHz. These components will form the basis for high performance RF photonic links with low noise figure, high SFDR and realistic operating optical power in the 100's mW range.

High-precision imaging technology and its application are highly demanded for the enhancement of civil security. They are used to help prevent major incidents in railways or airports. In these applications, both small object detection and high-range resolution are key features. As far as the detectable target size is concerned, a high-frequency carrier is indispensable in radar systems. However, a radio signal with millimeter-wave (high frequency) suffers from large atmospheric attenuation. For example, the attenuation coefficient at 90 GHz is estimated to be 1 dB/km, while it is less than 0.1 dB/km in microwave bands [1]. Thus, the radar signal will have to originate from an area close to the target. Setting up a radar system with a synthesizer close to the target might not be desirable because a high-precision electrical synthesizer is generally large and consumes high energy. Radio-over-fiber (RoF) technology, used to transport the signal over optical fibers, is a promising candidate to deliver the millimeter-wave signal to the suitable point over a low-loss optical fiber cable. Radars utilizing the RoF technology have already been reported; however, digital signal processing in remote radar heads was required to reduce large transmission data [2, 3].

This paper describes an “active” version of a hermetic fiber-optic feedthrough for avionic transceivers; active means that the Tx and Rx versions of the feedthroughs include a VCSEL array or a photodiode array, respectively. The hermetic feedthrough is an assembly of stamped components that align all of the optics to precision sufficient for single-mode applications. A stamped micro mirror array bends the light beams 90 degrees so that optical fibers are arranged parallel to the substrate. Active hermetic feedthroughs can be attached onto the ends of fiber-optic jumpers to make an active, mirrored, optical fiber sub-assembly (AM-OFSA). AM-OFSAs allow transceiver manufacturers to eliminate complex optical alignment processes within the hermetic package and only require low-tolerance electrical connections.

Infrared imaging (3-25μm) has been an important technological tool for the past sixty years since the first report of infrared detectors in 1950s. The ability to detect the temperature of a scene from the blackbody radiation that it emits has spawned applications in a wide variety of fields ranging from defense and security to non-invasive medical diagnostics and remote sensing. However, IR imaging landscape has dramatically changed in the past decade. Firstly, the cost of lower end imagers has been steadily declining (30% every year since 2005) enabling them to be mounted on dashboards of automobiles including Audis and BMWs. Secondly, advent of novel antimonide based semiconductor technology has dramatically improved the performance of higher end imagers that are used for military, defense and security applications. There has been a dramatic progress in the development of infrared detectors in the past decade with new materials like InAsSb, InAs/GaSb superlattices and InAs/InAsSb superlattices. However, in spite of dramatic technological progress, there are a lot of unknowns in these materials. For instance, the background concentration, vertical mobility, diffusion constants etc for these systems are largely unknown or are very difficult to measure accurately. The GaSb conducting substrate coupled with anisotropic transport and quantum transport makes the investigating of this system challenging.
