Color Symmetry Breaking in a Nonlinear Optical Microresonator
Laser &Photonics Reviews, EarlyView.A two‐color pump drives an integrated microring resonator into spontaneous color symmetry breaking mediated by the nonlinear Kerr effect. Above threshold, one optical color becomes spontaneously dominant while the other is submissive, with the selected output state emerging randomly. These results establish a new form of symmetry breaking in integrated

Noise in distributed erbium-doped fibers [PDF]
IEEE Photonics Technology Letters, 1993 Theoretical limits in noise figure for a long-haul transmission line based on lumped amplification are contrasted with distributed amplification. The latter results in a reduction of approximately 60% of the required number of pump power stations. The distributed optical amplification is provided by an erbium-doped fiber and comparisons of aluminum and
