Slow light with flat or offset band edges in few-mode fiber with two gratings.
نویسندگان
چکیده
We consider mode coupling in multimode optical fibers using either two Bragg gratings or a Bragg grating and a long-period grating. We show that the magnitude of the band edge curvature can be controlled leading to a flat, quartic band-edge or to two band edges at distinct, nonequivalent k-values, allowing precise control of slow light propagation.

Degenerate band edges in optical fiber with multiple grating: efficient coupling to slow light.
Degenerate band edges (DBEs) of a photonic bandgap have the form (ω-ω(D)) ∝k(2m) for integers m>1, with ω(D) the frequency at the band edge. We show theoretically that DBEs lead to efficient coupling into slow-light modes without a transition region, and that the field strength in the slow mode can far exceed that in the incoming medium. A method is proposed to create a DBE of arbitrary order m...
متن کاملLight Polarization-Assisted Sensing with Tilted Fiber Bragg Gratings
Tilted fiber Bragg gratings (TFBGs) are short-period gratings for which the refractive index modulation of the fiber core is angled by a few degrees with respect to the perpendicular to the propagation axis. They induce two kinds of light coupling: the self-backward coupling of the core mode at the Bragg wavelength and the backward coupling between the core mode and several tens of cladding mod...
متن کاملContinuous wave ultraviolet light-induced fiber Bragg gratings in few- and single-mode microstructured polymer optical fibers.
We report observations and measurements of the inscription of fiber Bragg gratings (FBGs) in two different types of microstructured polymer optical fiber: few-mode and an endlessly single mode. Contrary to the FBG inscription in silica microstructured fiber, where high-energy laser pulses are a prerequisite, we have successfully used a low-power cw laser source operating at 325 nm to produce 1 ...
متن کاملTransverse mode selection in laser resonators using volume Bragg gratings
Power scaling of high power laser resonators is limited due to several nonlinear effects. Scaling to larger mode areas can offset these effects at the cost of decreased beam quality, limiting the brightness that can be achieved from the multi-mode system. In order to improve the brightness from such multi-mode systems, we present a method of transverse mode selection utilizing volume Bragg grat...
متن کاملMultiwavelength fiber lasers based on multimode fiber Bragg gratings using offset launch technique
The reflective characteristics of a multimode fiber Bragg grating (MM-FBG) and the changes of reflective spectra with mode excitation conditions in the multi-mode fiber were investigated. Two multiwavelength fiber laser configurations using offset launch technique to MM-FBG with hybrid gain mediums are proposed and demonstrated. Different multiwavelength outputs were obtained by variation of th...
