Photonics Design Automation

Taking a Building Block Approach to Optical Chip DesignFuelled by an increasing demand for bandwidth combined with a continued drive towards cost and size reduction, larger scale photonics integrated circuits are now clearly breaking through. For example, fiber optics networks are rapidly embracing 40Gbps and 100Gbps data rates, where the transmitters and receivers often include photonic integrated circuits. And the cost and size reduction in 10Gbps transceivers has driven several companies to successfully leverage photonic chips. The growing FTTH (fiber to the home) market is driving demand for integrated photonic splitters as well as monolithically integrated BiDi transceivers. And there are exciting applications in fiber sensing and bioscience that are now benefiting from optical chips as well.

3D Imaging Sensor

FSI Technologies (Lombard, IL) has added a new 3D imaging sensor to its machine vision product line. The GS Family of 3D imaging sensors provides support to a whole new range of robot control and inspection applications. The GS 3D sensors, when used in conjunction with the PowerEye machine vision system, can be used in applications such as bin picking, robotic manipulation, sorting products, mold clearance checking, and space monitoring and object recognition. In addition, the 3D technology will aid in determining spatial positions and measurements.

C-mount Spectrometer Adapters

A new series of adapters, simplifying integration of c-mount cMOS and CCD cameras with McPherson (Chelmsford, MA) high performance spectrometers, is now available. Easy and secure c-mount adapters are suitable for cryogenic, TEcooled, deep depletion, near infrared In- GaAs, and sensitive Silicon visible range cameras. They fasten via 1-inch, 32-pitch screw thread with 17.526mm back distance to focal plane. The new McPherson adapters have a nested design to accommodate the threaded, rotating c-mount.

2.8 MP GigE Vision Camera

Point Grey (Richmond, BC, Canada) recently announced the addition of new 2.8 megapixel models to its Flea®3 line of GigE Vision digital cameras. Building on Point Grey’s experience with Sony CCD technology, the Flea3 FL3-GE- 28S4 monochrome and color models use the all-new, highly sensitive Sony ICX687 EXview HAD CCD II™ image sensor to deliver high resolution, high quality images in a compact and low-cost package. The Sony ICX687 builds on the success of the popular ICX274 2MP CCD by offering more pixels and better sensitivity in the same 1/1.8" optical format.

Cool Bypass Switches

STMicroelectronics (Geneva, Switzerland) has introduced its latestgeneration high-efficiency cool bypass switches for photovoltaic modules, enabling an even higher percentage of harvested energy to reach end-users and further reducing the cost per Watt of renewable energy. The new devices can save up to 1% of the energy produced and normally lost through conventional bypass diodes; in a 1MWp solar array farm this loss could provide the total annual electricity consumption of two average European households.

Multi-Channel Laser Modules

AKELA Laser Corporation (Monmouth Junction, NJ) announced the release of its single and multi-channel laser diode modules in wavelengths from 635nm to 1950nm. The second in a series of releases over the next 6 months, these modules offer integrated cooling and drive electronics for plugand- play use. Suitable for both R&D and OEM applications, they are designed for 100 micron, 0.22NA fibers and provide up to 2 Watts CW per channel. Future product releases will include increasingly higher power levels as well as modules designed for the medical market with built-in accessories such as photodetectors, aiming beams, blast shields, and fiber sensors. The laser modules are available in the following configurations: single channel; multi-channel with independently addressable outputs; and multiple outputs controlled by a single driver.

Chip-Based Video Camera

Lattice Semiconductor Corporation (Bridgewater, NJ) recently demonstrated a LatticeECP3-based video camera supporting NIT’s NSC1005 Wide Dynamic Range (WDR) 720p image sensor. The NSC1005 high dynamic range image sensor from NIT (Verrieres le Buisson, France) is available mounted on a headboard, called the Widy Board, complete with lens and is intended for use with the Lattice HDR-60 Video Camera Development Kit. The sensor is fully supported with a 60 frames per second color Image Signal Processing (ISP) pipeline implemented on a LatticeECP3(TM) FPGA. The hardware is designed to support full 720p resolution of the NIT NSC1005 sensor at 60fps in streaming mode through the FPGA, without the need for an external frame buffer. Other features include high-quality DeBayer operating in the log domain, Auto White Balance, Gamma Correction and Overlay for both character and graphics. Lattice HDMI PHY IP enables output to HDMI/DVI monitors.
