Abstract: Abstract. A silicon photonic crystal (PhC)-based structure is proposed to efficiently couple power from two different wavelengths, targeted to the application of an integrable Raman amplifier. The coupler uses two asymmetrical PhC waveguides as input… read more here.

Abstract: Fiber-integrated, submersible-qualified, core-pumped, multicore EDFAs are indispensable for space-division-multiplexing envisioned for the next generation of submarine communication lines. Here we demonstrate a fully packaged, 63-dB counter-propagating crosstalk, and 70-dB-return-loss four-core pump-signal-combiner. This enables core-pumping of… read more here.
