Toward transmission applications with microstructured fibers

Abstract

Recent progress of microstructured fibers for optical transmission has been described. We demonstrate potentiality of the fiber for future ultra high capacity optical transmission systems, which are not realized with a conventional single-mode fiber.

Novel Dispersion Properties of Photonic Crystal Fiber

“…PCF technology has advanced now to the point that km-lengths of robust coated fiber can be produced with losses as low as 0.28 dB/km. 24) Such fibers with a broad range of unique and useful optical properties should have the potential to enable a variety of practical optical devices, nonlinear or linear for a wide range of applications areas, both within telecommunications and beyond.…”

Progress of photonic crystal fibers and their applications

“…The attenuation at 1310 and 1550 nm for total internal reflection (TIR) PCFs is 0.35 dB/km and 0.205 dB/km, respectively [10], which is nearly the same level as the common single-mode optical fibers. The hydroxyl absorption at 1383 nm is below 1.0 dB/km [11]; the attenuation for hollow core PBG fibers is decreased from 1.7 to 1.2 dB/km at 1620 nm [12]. The main applications of PCFs are formulated in the following.…”

“…The ultra wide single-mode region of PCF has provided the possibility of a 1000 nm band in PCF for 40 Gb/s optical communication [48][49][50]. With flat chromatic dispersion, a large effective mode area and low leakage losses, a new kind of PCF has been proposed for the S + C + L telecommunication band.…”
