Ultralinear bistable electro-optic polarization modulator

Albert Feldman

Published Aug 1, 1978• 30 citations
Publisher

Abstract

An optical device utilizing optical feedback has been constructed with a Pockels cell and polarizing components. Two modes of operation of the device are demonstrated. Both modes exhibit optical bistability. It is demonstrated that in one mode of operation the nonlinear dependence of the output intensity as a function of an input optical or electrical signal can be made arbitrarily small compared to the linear dependence.

Bistable optical systems based on a Pockels cell

Albert Feldman

The performance of a bistable intensity modulator based on a Pockels cell can be optimized if a voltage proportional to a linear combination of input and output intensities is applied to the Pockels cell. The bistable response can more closely approximate a step function. The output-optical-power regulation can be improved at levels close to the input-power level. The operating point of an ultralinear modulator can be maintained at the most linear portion of the response curve. Some of the above features are demonstrated experimentally. Analogous modifications can be made to advantage on other bistable optical systems.

Optical bistable device as electro-optical multivibrator

W. Sohler

A truly bistable device using an integrated optical cutoff modulator in LiNbO3 is reported. With appropriate optical input power, the device may be used as an electrical Schmitt trigger (electrical bistability). By electrical feedback, electro-optical multivibrator operation is demonstrated.

A BISTABLE LIQUID CRYSTAL ELECTRO-OPTIC MODULATOR

Hongjun Zhang, DAI JIAN-HUA, Junhui Yang +2 more

A new liquid crystal hybrid bistable optical device (BOD) is introduced. The optical bistability of two modes of operation of this LC BOD have been observed. The use of LC BODs for optical logic elements and ultralinear modulation applications is described. The transient response of LC BODs has been studied and a "critical slowing down" phenomenon has been observed. The switch time has been measured. The experimental results are in agreement with Garmire's theory.

An electrooptic nonlinear Michelson optical bistable devices

Li C

An electrooptical crystal was inserted in one of the two arms of a Michelson interferometer. The feedback signal was used for phase modulation of the light beam in this arm. Thus the light output intensity, as a result of the interference of two beams, exhibited optical testability. An integrated optical device version based on this principle was proposed.

Optical bistable devices as sensing elements

Ana Pilar Gonzalez-Marcos, Antonio Hurtado, José A. Martín-Pereda

The nonlinear optical properties of many materials and devices have been the main object of research as potential candidates for sensing in different places. Just one of these properties has been, in most of the cases, the basis for the sensing operation. As a consequence, just one parameter can be detected. In this paper, although just one property will be employed too, we will show the possibility to sense different parameters with just one type of sensor. The way adopted in this work is the use of the optical bistability obtained from different photonic structures. Because this optical bistability has a strong dependence on many different parameters the possibility to sense different inputs appears. In our case, we will report the use of some non-linear optical devices, mainly Semiconductor Optical Amplifiers, as sensing elements. Because their outputs depend on many parameters, as the incident light wavelength, polarization, intensity and direction, applied voltage and feedback characteristics, they can be employed to detect, at the same time, different type of signals. This is because the way these different signals affect to the sensor response is very different too and appears under a different set of characteristics.

Electrical simulation of optical bistability

K. Daneshvar, Gilbert U. Singco

The electrical equivalence of optical bistability consists of a circuit with input V/sub i/, output V/sub 0/, and transmission T(V/sub 0//V/sub i/) which is nonlinear with respect to input. A circuit with the above characteristics has been constructed. This circuit consists of a dissipative resonator with voltage-controlled capacitors and resistance as nonlinear elements. It is shown that bistable electric resonance circuits can function as an electrical equivalent with many important characteristics of an optical bistable device.>
