Design of photonic band gap fibers with suppressed higher-order modes: towards the development of effectively single mode large hollow-core fiber platforms.
The objective of the present investigation is to propose and theoretically demonstrate the effective suppression of higher-order modes in large-hollow-core photonic band gap fibers (PBGFs), mainly for low-loss data transmission platforms and/or high power delivery systems. The proposed design strategy is based on the index-matching mechanism of central air-core modes with defected outer core mo...
متن کاملSurface modes in air-core photonic band-gap fibers.
We present a detailed description of the role of surface modes in photonic band-gap fibers (PBGFs). A model is developed that connects the experimental observations of high losses in the middle of the transmission spectrum to the presence of surface modes supported at the core-cladding interface. Furthermore, a new PBGF design is proposed that avoids these surface modes and produces single-mode...
متن کاملDynamic control of higher-order modes in hollow-core photonic crystal fibers.
We present a versatile method for selective mode coupling into higher-order modes of photonic crystal fibers, using holograms electronically generated by a spatial light modulator. The method enables non-mechanical and completely repeatable changes in the coupling conditions. We have excited higher order modes up to LP(31) in hollow-core photonic crystal fibers. The reproducibility of the coupl...
متن کاملAir-core photonic band-gap fibers: the impact of surface modes.
We study the dispersion and leakage properties for the recently reported low-loss photonic band-gap fiber by Smith et al. [Nature 424, 657 (2003)]. We find that surface modes have a significant impact on both the dispersion and leakage properties of the fundamental mode. Our dispersion results are in qualitative agreement with the dispersion profile reported recently by Ouzounov et al. [Science...
متن کاملSynthesis of Electromagnetic Modes in Photonic Band Gap Fibers
In this paper, we report on the successful synthesis of three individual modes, HE11 , TE01, and TE 02 for transmission in photonic band gap fibers at near infrared wavelengths. We measure the propagation losses of the HE,1 and TE0 1 modes both inside and outside the band gap of the fiber, and show that the TE0 1 is indeed the lowest loss mode, and is less lossy and has a much wider band gap th...
