Technology

AdValue Photonics' fiber laser and broadband ASE (amplified spontaneous emission) light source products are empowered by our core technology - proprietary specialty glasses and innovative non-silica gain fibers. Our unique technology gives our products the advantages of higher gain and higher output power over a shorter fiber length, broader gain bandwidth, and significantly lower optical nonlinearity as compared to light source devices based on silica fibers. It makes light generation and amplification at wavelengths and intensities otherwise beyond reach.

AdValue Photonics' gain fibers are suitable for fusion splicing with standard silica fibers, producing joints chemically stable and mechanically durable. A wide variety of fiber types can be readily engineered for specific fiber based device designs, including truly single mode fibers with large mode area, double cladding fibers, triple cladding fibers, polarization maintaining (PM) gain fibers, and photonic crystal fibers. Other types of fibers can be designed and fabricated include double cladding fibers with external glass cladding, fibers with numerical aperture (NA) greater than 0.6, etc. An important advantage of our non-silica fibers is that they are immune to photodarkening which is a deficiency associated with heavily rare-earth doped silica fibers.
