Multi-channel mode converters based on in-line fiber modal interferometer
2017
2017 Opto-Electronics and Communications Conference (OECC) and Photonics Global Conference (PGC)
A modal interferometer was proposed to realize multichannel mode conversion in two mode fiber. The near-filed pattern confirmed the LP01 mode was converted into LP11 mode at the destructive wavelengths. The mode conversion was realized at 20channels in the C+L wavelength band with conversion efficiency up to 99.5% and insertion loss lower than 0.6 dB.
