Lasers incorporating two-dimensional photonic crystal mirrors [PDF]

, 1997
Photonic bandgap crystals are expected to be of use in defining microcavities for modifying spontaneous emission and as highly reflective mirrors. There are several reports of microfabricating one-dimensional structure.

Coexisting periodic attractors in injection locked diode lasers [PDF]

, 1997
We present experimental evidence for coexisting periodic attractors in a semiconductor laser subject to external optical injection. The coexisting attractors appear after the semiconductor laser has undergone a Hopf bifurcation from the locked steady ...
