Exhibitor profiles: Part 5

Multiwave Photonics
Multiwave Photonics offers innovative optical sources based on fiber-optic technologies, as well as product design and engineering services aimed at developing cost-effective and reliable products. The company, which was founded in Maia, Portugal, in 2003, says it is aiming to become a "world-class" supplier of fiber-optic sources and sub-systems for applications in instrumentation, medicine and industry.
The company has just released a multi-point fiber-optic temperature system for "hot-spot" monitoring. The instrument can be fitted inside an oil-filled power transformer, since it is electrically passive, immune to EMI noise and controlled remotely.

Oerlikon Optics
Oerlikon Optics produces coated optical components and subassemblies for a diverse set of industries incorporating optics and photonics. The company is also a leader in consulting, prototyping, and volume production of optical thin-film products, and in producing in color management systems for all major microdisplay technologies.
In 2006 Oerlikon bought UK company Exitech, which is considered to be one of the leading providers of nano- and microlaser systems worldwide. Exitech will be integrated in the Oerlikon Optics business unit, but the company's solar and wafer processing business units are also expected to benefit.
New-generation bandpass filters from Oerlikon have also been integrated into novel optical sensors that are designed to increase safety in road traffic control. The company is now exploiting its customized sputter technology to produce the bandpass filters in high volumes. The sputter technology achieves dense coating layers, which offer much better environmental resistance than those produced by conventional coating processes.

R Soft
RSoft Design Group offers a comprehensive suite of design and business analysis software solutions to the telecommunications, photonics and semiconductor industries. It provides a full range of simulation and planning software and services across the entire component to network-level hierarchy. These products are used by researchers, manufacturers, systems integrators, and service providers to address design challenges ranging from the physics of component design to the business implications of planning networks.
RSoft has just launched a CAD system to support its own RSoft Component Design Suite. The latest CAD version adds 3D editing capability, a more streamlined design process, and an updated appearance to RSoft's flexible and user-friendly CAD interface. All of RSoft's passive device simulation tools, including BeamProp, FullWave, BandSolve, GratingMod, DiffractMod, and FemSim will take advantage of the new CAD environment.

Scitec Instruments
Scitec Instruments, which has been based in Cornwall in the south west of England since 1991, produces what it describes as "the widest range of rotating disc optical choppers”. The devices operate up to 120 KHz, and range in diameter from 30 to 200 mm. The company has also developed its own range of lock-in amplifiers - the newest being based on FPGA technology.
Scitec also acts as a distributor for a number a European and US companies, and has just opened a Polish division, Scitec Instruments Polska (SIP). Besides the products Scitec offers in the UK, SIP also represents CVI Laser, Lasermet, Laser Beam Products and ICX Photonics.

Stocker Yale
Over the past 50 years, StockerYale has introduced diverse lighting applications to the optical and metrology industries. The company is an independent designer and manufacturer of structured light lasers, LED modules, and fluorescent lighting products, as well as specialty optical fibers and phase masks for industry leading OEMs. Through this diverse product mix, the company serves a wide range of markets including the machine vision, industrial inspection, defense, telecommunication, sensors, and medical markets.
In addition, StockerYale supplies a complete suite of fibers for the fabrication of fiber lasers. The suite includes rare-earth doped active fibers, mode-matched photosensitive fibers for fiber Bragg gratings (FBGs), as well as passive fibers for the delivery of pump and laser light.
The company has just released a new erbium-doped amplifier fiber, known as EDF-T9. The fiber exploits the company's proprietary doping method, which offers the ability to control aluminum content with an unsurpassed degree of precision.
StockerYale is also expanding in the area of short-wavelength single-mode products. The new short-wavelength fibers will serve in applications such as RGB imaging systems, laser diode pigtails, along with other specialized applications involving single-mode delivery of visible and near UV light. Meanwhile, a new range of circular-polarization-maintaining fibers have been designed for use as the sensing fibers in optical current sensors.

TEM Messtechnik">TEM Messtechnik
TEM Messtechnik, which has been involved in laser technology since the company was founded in 1998, manufactures a wide range of instruments either in its own right or in partnership with other specialist companies. Its iScan system, for example, is a universal instrument for static and dynamic testing of tunable lasers. It allows for fast and precise scanning of tunable lasers, surveillance of the scan behavior of tunable lasers, stepping to different arbitrary wavelengths and measurement of the wavelength stability of tunable lasers.
The device comprises a measurement head and the control electronics unit. The head contains interferometer optics, photo detectors, preamplifiers and temperature sensing. The company's DL100/110 series features modules for the precise control of diode lasers and the acquisition of measurement data. Different modules can be combined in a versatile rack to satisfy a variety of applications, but only three modules - power and monitoring, diode current control and temperature control - are needed for basic operation.
