This means that in order to keep the routing tables consistent and to maintain mode compatibility, appropriate actions need to be taken.
Simulation results show that the parabolic-profile single-mode fiber could support both an ultra-low bending loss (0.052 dB/turn at bending radii R=5 mm) and a large effective mode area up to 260 μm2 at 1.55 μm, meanwhile maintaining single-mode operation rigorously (cutoff wavelength fixed at 1.26 μm).
The STED laser was further sent through SF6 glass rods (SF6) and a 120 mlong polarization maintaining single-mode fiber (PMS) for stretching of the pulses and mode cleaning.
Design of the fiber ensures no intermodal coupling, low bending loss, and high fabrication tolerances while maintaining large-mode-area.
Polarization maintaining two-mode photonic crystal fiber (PMTMPCF) is preferred because it can be designed and fabricated to satisfy the criterions.
In this paper, we propose a highly birefringent and highly nonlinear polarization maintaining single mode hybrid cladding circular photonic crystal fiber (HyC-CPCF).
Although in the case of brittle, isotropic and homogeneous solids, cracks propagate by maintaining pure mode-I condition at the crack tip, the stress field that triggers debonding at an interface can be very complex (Hutchinson and Suo 1992).
The method of designing the fiber parameters is described while maintaining single mode oscillation, such as R1=1, R2=0.75, a=85 μm, L=10 cm, N=5×1020 cm−3, and threshold power is 6.3 W.
A twin bow-tie polymer-based photonic quasi-crystal fiber with high birefringence, high nonlinearity and low dispersion as well as maintaining single mode operation is presented in the wavelength range 1.8 2.2 μm.
Pilot testing suggested that the fixed regularize/read ordering was most effective for establishing and maintaining task mode.
