Photonics West 2012 Product Presentation by Dr Andy Gillooly: RGB - UV Fibers

Broadband Fibers for use at 305 nm - 450 nm and 450 nm - 800 nm




With the growing use of fibers in Medical and Spectroscopy applications, the need to transmit red, green and blue light down a single fiber is an increasingly important requirement.


The broadband performance of the Fibercore SM450 specialty singlemode fiber is perfect for these applications where the high NA insures that, even with the fiber coiled, bend-losses are kept to a minimum across the full broadband range, from 450 nm to 800 nm. The all-silica SM300-SC and SM400-SC fibers extend the wavelength range into the UV and are ideal for use from 305 nm to 450 nm, where the absense of Germania in their core significantly reduces photodarkening at blue and UV wavelengths.





Our second presentation at this year's Photonics West Exhibition in San Francisco will be showcasing these fibers, so if you are attending the show and want to know more, then come along to North Hall D, Demo Area 2, at 4.30 pm on Tuesday 24th January 2012 where Dr Andy Gillooly will introduce the fibers to you.

Photonics West 2012 Product Presentation by Dr Andy Gillooly: SM-P Polyimide Coated SM Fibers

New Polyimide Coated Singlemode Fiber for Embedded and High Temperature Applications


Optical fiber sensors have been widely adopted into a range of sensing technologies including discrete and continuous temperature, pressure and strain sensors often used in relatively benign environments. Typically these sensors have been used in pipeline monitoring, perimeter monitoring, heat detection and structural monitoring systems, all of which operate within the -45 degrees C to +85 degrees C temperature range of a standard optical fiber.


As industries push their sensing requirements into the high temperature environments in oil wells and nuclear reactors or into the tight coil requirements for hydrophones and seismic sensing geophones, optical fibers start to offer major technical benefits over electronic sensors. Fibers can be designed to tolerature the high temperatures and pressures found in oil wells, they can be radiation tolerant for nuclear environments, are immune to the high levels of electro-magnetic interference (EMI) associated with large industrial machinery and they do not require electrical power at the sensing element - particularly important for subsea reliability.


Extracting oil and gas from wells has become increasingly difficult and fiber sensors are being used more and more to enhance oil recover. The downhole environment of this industry is extremely aggressive with temperatures exceeding 300 degrees C and, whilst a high temperature acrylate coating can be used for applications working at around 150 degrees C, demand a fiber with a high-performance coating.


Fibercore's high NA, bend-insensitive specialty singlemode fibers are already widely used in sensor application all over the world and we have built on this technology to offer a new range of polyimide coated, bend-insensitive singlemode fiber, specifically designed for the seismic sensors and distributed sensors used in these highly challenging environments of the oil and gas explorations industries and other similar industries. Using the polyimide coating of our HB-P polarization maintaining fibers, these singlemode fibers offer the same bend insensitivity and photosensitivity of our high NA SM fibers with the added advantage of being able to withstand short-term temperatures as high as 400 degrees C (and 300 degrees C continuous).


Our first Product Presentation at this year's Photonics West Exhibition in San Francisco will be showcasing this new range of fibers, so if you are attending the show and want to know more, then come along to North Hall D, Demo Area 2, at 11.30am on Tuesday 24th January where Dr Andy Gillooly will introduce the fibers to you.

Photonics West 2012












With Photonics West 2012 just two weeks away, Fibercore Ltd are pleased to announce that, once again, we will be exhibiting at this, the World's largest photonics and laser event. As well as being available to discuss the wide variety of specialty singlemode fibers that we offer, ranging from the World famous and market leading reduced-clad HiBi PM fibers to our all-glass Er/Yb co-doped dual-clad cladding pump fiber for high power amplifiers, Dr Andy Gillooly will be making two presentations during the event to highlight our recent product additions to our specialty singlemode fiber ranges.


Our first presentation announces the arrival of a new range of polyimide-coated singlemode fibers designed for embedded and high-temperature applications. Based on our SM1500 fibers, they combine the bend-insensitivity and intrinsic photosensitivity of these high NA singlemode fibers with the polyimide-coating of our HB-P fibers, enabling them to withstand temperatures as high as 400 degrees C (or 300 degrees C continuous), and making them ideal for the highly challenging environments of industries like oil and gas explorations.



The design wavelengths of the fibers in our specialty singlemode fiber range start as short as 450nm for tranmission in the UV to the Red range, and our all-silica SM-SC fibers offer even shorter wavelengths of 300nm to 400nm. Our second presentation concentrates on these R(ed), G(reen),B(lue) fibers and their use in spectroscopy, biotechnology and LDA applications.



So if you would like to know more about our fibers and how they can help your applications, visit us at Photonics West 2012 Booth 4926, which will take place at the Moscone Center, San Francisco, from 24th to 26th January 2012.
