We report highly efficient four wave mixing in a GaInP photonic crystal waveguide. Owing to its large bandgap, the ultrafast Kerr nonlinearity of GaInP is not diminished by two photon absorption and related carrier effects for photons in the 1550 nm range. A four-wave-mixing efficiency of -49 dB was …

We report highly efficient four wave mixing in a GaInP photonic crystal waveguide. Owing to its large bandgap, the ultrafast Kerr nonlinearity of GaInP is not diminished by two photon absorption and related carrier effects for photons in the 1550 nm range. A four-wave-mixing efficiency of −49 dB was demonstrated for cw pump and probe signals in the milliwatt range, while for pulsed pumps ...

We propose a scheme to obtain a highly efficient four-wave mixing (FWM) in a coherent six-level tripod system by using a double-dark resonance and multiphoton destructive interference induced transparency. We show both analytically and numerically that the optical-wave mixing in such a system with a pump wave and an internally generated FWM wave mediated by …

Highly Compact and Efficient Four-Mode Multiplexer Based on Pixelated Waveguides Abstract: An ultra-compact mode multiplexer for TE 0, TE 1, TE 2 and TE 3 modes is proposed and demonstrated experimentally. The device is realized via pixelated waveguides with a footprint of only 5.4 × 6μ m 2. The measured insertion loss of the multiplexer is ...
