Unidirectional ring resonator in photorefractive bismuth silicon oxide with two pump beams

Abstract

Experiments using a new photorefractive gain mechanism involving two pump beams are described. A ring resonator is used to provide a frequency-shifted signal beam. The gain with two pumps of equal intensity is found to exceed that with a single pump by about a factor of 4.

Bistable resonator utilizing saturable photorefractive gain and loss

Diana M. Lininger, Peter J. Martin, Dana Z. Anderson

We report the observation of bistability in a unidirectional ring resonator that employs photorefractive barium titanate for gain and also for saturated loss. One photorefractive crystal provides gain via two-beam coupling in a conventional unidirectional ring configuration.1 A second crystal is arranged to couple light out of the resonator using two-beam coupling, thereby producing loss. The orientations of the two crystals are chosen so that the magnitude of the small signal loss is greater than the magnitude of the small signal gain. Thus the oscillation in the ring cannot build up from noise since there is no net gain. However, the pump intensity for the gain medium is made larger than that for the loss medium. This means that the loss saturates at a lower signal level. Hence, at large intensities, gain can exceed net loss so oscillation can occur.

Competition between subharmonic and resonating beams for photorefractive gain in bismuth silicon oxide

D. C. Jones, LASZLO SOLYMAR

Two beams incident upon a bismuth silicon oxide crystal are shown to give rise to a subharmonic halfway between the incident beams and to an oscillating beam in a ring resonator. It is further shown that the two beams arising are in competition with each other: the subharmonic power rises when the oscillating beam declines owing to damping of the resonator.

A unidirectional photorefractive ring resonator oscillating at 633 nm

Hong Lin, David W. Weir, Adnan Yousuf +1 more

We have constructed an optical resonator using a photorefractive crystal as the gain medium. The orientation of the crystal and the angle between the signal and the pump beam are chosen to obtain optimal two-wave coupling. The average output power of the resonator is proportional to the power of the pump beam for a small cavity loss, but this linear relation is broken when the cavity loss is increased. The transverse beam pattern of the signal can be controlled by intracavity apertures.

Bistable ring resonator utilizing saturable photorefractive gain and loss

Diana M. Lininger, Peter J. Martin, Dana Z. Anderson

We demonstrate the bistable behavior of a unidirectional ring resonator that employs photorefractive loss as well as photorefractive gain. The gain and loss are established by two-beam coupling in two separate photorefractive BaTiO(3) crystals. Two-beam coupling loss plays the role of a programmable saturable absorber. Irreversible bistability occurs when the maximum net gain exceeds unity, while reversable bistability is obtained when the maximum net gain is less than one.

Photorefractive flip-flop

Dana Z. Anderson, Claus Benkert, Beth Chorbajian +1 more

We demonstrate an optical flip-flop that consists of two unidirectional ring resonators that are coupled competitively through two-beam interactions in a photorefractive BaTiO(3) crystal. This crystal provides an active loss for each ring that depends on the oscillation intensity of the other. The coupled rings exhibit flip-flop bistability when the net gain, given by the product of the passive cavity losses and the gain, is greater than unity but is less than the small-signal active loss. The state of the system can be switched with an injected signal.
