The transverse asymmetry of the index modulation profile in the asymmetric few-mode fiber Bragg grating (FM-FBG) was investigated. The transverse asymmetry of the index modulation profile will lead to mode conversion between modes with the different azimuthal orders, and this asymmetry is characterized by the attenuation coefficient α. We evaluated that the value of attenuation coefficient α was 0.2 μm−1, and grating amplitude χ was 2.8 × 10−4 for FM-FBG inscribed by UV single-side illumination. We found that the optimized value of α was 0.16 μm−1, at which the maximum mode conversion efficiency of LP01–LP11 can be achieved. The results of this paper provide great potential application in few-mode fiber (FMF) devices and mode division multiplexing (MDM) optical communication.

AbstractWe present a novel mode-interference based polarization rotator with a dual-waveguide structure based on the standard silicon-on-insulator substrate. The polarization rotator section consists of two non-identical nanowire waveguides arranged 45° offset with regard to the other. Two identical dual-taper sections are introduced in-between this polarization rotator and the standard silicon input/output waveguides to realize equal modal excitation amplitudes of two hybrid modes in the polarization rotator section. Simulation results show that this device with the total length of 25.3 μm has the insertion loss of −0.51 dB and the extinction ratio of 32.27 dB for TM → TE mode conversion at the wavelength of 1550 nm and the extinction ratio of over 20 dB at thewavelength ranging from 1536 nm to 1568 nm.
