Phase-locked degenerate backward wave optical parametric oscillator
We report a self-phase-locked and degenerate backward wave optical parametric oscillator (BWOPO) generating a counterpropagating signal and an idler in the spectral Figure Skating - Accessories - Leg Warmers band of optical communication.The device is based on a periodically poled Rb-doped KTiOPO4 crystal with a poling period of 433 nm.To the best
