Where to Buy Optical Filters

Our OTDR FBG filters can be used for precisely analyzing power losses in fiber-optic telecom systems with optical time domain reflectometry (OTDR). They reflect the OTDR signal while fully transmitting (not disturbing) the data signal.

UltraFast Innovations (UFI) offers spectral filters for ultrashort pulse applications – for example, for preserving the pulse duration of reflected or transmitted pulses.

By using such spectral filters, researchers from Prof. Krausz’s group were able to build a so-called wave synthesizer. We were able to split or combine radiation from 250 to 1100 nm in four channels: 250–290, 290–350, 350–500, and 500–1100 nm. The phases of reflection and transmission are controlled. This allows one to precisely combine radiation from four channels, both spatially and in time, resulting in the generation of sub-optical-cycle pulses. Based on that technology, we also offer the first commercial light field synthesizer.

iXblue’s gain flattening filter based on fiber Bragg grating technology represents an easy and effective solution to flatten the gain in a WDM systems. The high accuracy (very low ripple) allows the use of cascaded filters, and the return loss is high (low reflections).

The IXC-FBG-PS bandpass filter has a sharp resonance peak in the transmission spectrum with less than 1 dB of insertion loss. It can be used in telecom as well as in sensing applications, also for distributed feedback (DFB) fiber lasers.

iXblue offers a broad range of Fiber Bragg Gratings (FBG) to address a wide array of applications in telecommunications, sensing, harsh environments, research and development, etc.

The excellent know-how in the FBG manufacturing process gives iXblue the capability to produce various filters on a variety of in house fibers. We stand ready to adapt our services to your needs from quick prototyping to volume production.
