More than 20,000 members of the worldwide photonics community gathered in San Francisco's Moscone Center this week for SPIE Photonics West 2012, the year's most anticipated photonics, lasers, and biomedical conference and exhibition. One of the biggest draws is the Photonics West Exhibition, and attendees could see the latest technologies and get information from more than 1,200 companies, universities, labs, and other exhibitors. Obviously, Photonics Online couldn't get around to every booth at this massive event, but we did visit quite a few. Most exhibitors with whom we spoke reported strong sales leads and were happy with the amount of traffic at their booths.
“It was a busy, uplifting show,” said Doug Malchow, Business Development Manager – Industrial Products, Sensors Unlimited – Goodrich ISR Systems. “The aisles were busy continuously throughout the show. There were great conversations, good meetings, and people are looking toward the future and willing to commit funds.”
Here is a rundown of some of the products we saw, people we met, and things we heard on Tuesday at the 2012 Photonics West Exhibition.
Abrisa Technologies highlighted its high ion exchange (HIE) thin glass, which is chemically strengthened in a post-production chemical process, greatly increasing the strength of the glass over that of float glass. This strong, flexible glass is extremely durable and damage-resistant, which makes it suitable for use in electronic devices, including smartphones, tablets, PCs, displays, touch screens, and TVs. The HIE thin glass allows for very sleek touch screen and display devices with better brightness and touch sensitivity. The glass is easy-to-clean, wear-resistant, and available in thicknesses from 0.5 mm to 2.0 mm. Precision cutting and machining, edge treatments, opposed drilling of holes, and custom screen prints all can be applied.
Accumold was on hand discussing their micro-injection molding capabilities - a large portion of their business is in micro-optics. They are molding objects from about 3½” in diameter to 800 microns tall. “Conversion from glass to plastic is becoming more and more common in photonics or telecommunications, imaging, cameras, you name it,” said Aaron Johnson, marketing manager at Accumold. “The fastest-growing area of interest involves diffractive or microstructures on the surface of plastics, where you get into sub-micron feature details.” Accumold recently opened a $7 million, 44,000-square-foot expansion that added 43 employees to its workforce and more than doubled the size of its facility.
CeramOptec highlighted a range of fiber optic solutions, including non-circular core silica optical fibers and bundle assemblies. The non-circular core silica optical fibers are offered in square, rectangular, octagon, hexagon, and V-shapes. A square fiber offers a more stable means of transmission than that of a circular core fiber as the spatial power distribution is more constant. Good image scrambling is characteristic of the square core fiber, and together with its low focal ratio degradation (FRD), improves image processing, making them ideal for astronomy applications. Because of their construction, bundles offer light management and physical flexibility. Manufacturing custom bundle configurations is CeramOptec's specialty — any fiber, any design, for any application.
CMC Electronics showcased their four-channel hermetically sealed fiber optic transceiver for military aircraft, commercial aircraft, UAV, UAS, and surface and subsurface watercraft. The transceiver incorporates proprietary ruggedization techniques suitable for applications requiring 100% reliability in extremely harsh environmental conditions and features 4 RX + 4TX channels (individually enabled), 12-fiber 50-µm core ribbon cable with MT termination, 2.125 Gbps/channel, capability up to 10 Gbps, operating temperature of -50°C to 115°C, and a weight of less than 12 g. “This transceiver has its roots in the Joint Strike Fighter Program, ” said Al Mottola, account manager, custom electronics, at CMC Electronics. “It is immune to most environmental conditions due to its hermetic design criteria.”
In addition to their regular lineup of emitters, LEDs, photonic detectors, and thermal infrared detectors, Excelitas showcased the new C30737CH Series silicon avalanche photodiodes (APDs). These APDs come in a side-looking LLC (laminated leadless carrier) package and are ideal for laser meter, range-finding, and area scanning applications. The LLC package has a distinct advantage over traditional thru-hole packaging because it allows for automated pick-and-place “side-looker” assembly on printed circuit boards. It also allows optical design for laser meter and range finding applications in the 500- to 1000-nm range. Additional areas of application include speed guns, optical communications, 3D laser scanning, and gesture recognition.

Boston Micromachines displayed the MEMS Optical Modulator, which was designed for use in free space optical communication systems. The modulator is a reflective diffraction grating with controllable groove depth. In the powered state, the MEMS Optical Modulator diffracts light, and in the unpowered state it reflects the light back. By bouncing a beam of any type of light off of it you can use it to modulate the light in a very quick binary type of fashion or you can use it to vary the intensity. The MEMS Optical Modulator design is based on Boston Micromachines’ heritage deformable mirror technology that uses hysteresis-free electrostatic actuators to periodically deform a continuous mirror facesheet.
Imec offered the first public showing of a hyperspectral camera solution based on a system-on-chip image sensor with an integrated hyperspectral sensor. It can achieve scanning speeds compatible with industrial requirements due to its integrated filter design and high spectral filter efficiency. Imec's fully integrated CMOS-compatible hyperspectral sensor consists of a set of spectral filters that are directly post-processed at wafer level on top of a commercially available CMOSIS CMV4000 image sensor (a 4-megapixel sensor with a maximum frame rate of 180 fps). Also at the show, imec and Genalyte announced that they have developed and produced a set of disposable silicon photonics biosensor chips to be used in Genalyte diagnostic and molecular detection equipment.
