Demonstration of a mid infrared silicon Raman amplifier
Varun Raghunathan, David Borlaug, Robert Rice +1
We demonstrate for the first time a mid infrared silicon Raman amplifier. Amplification of 12 dB is reported for a signal at 3.39 micron wavelength. The active medium was a 2.5 cm…

Self-imaging silicon Raman amplifier
Varun Raghunathan, Hagen Renner, Robert R. Rice +1
We propose a new type of waveguide optical amplifier. The device consists of collinearly propagating pump and amplified Stokes beams with periodic imaging of the Stokes beam due to…
