Hybrid Optoelectronic Bistability in Frequency-Domain and Its Potential Application in FBG Sensors

Abstract

We propose a novel optical bistable device (OBD) in frequency-domain with which we can perform optical bistable operations in a number of fibre Bragg gratings (FBGs) which are included in the same OBD. Such an OBD may bring more opportunities in applications and, as an example, we show the possibility of using it in an FBG sensor demodulating system. By use of a tunable light source, consisting of a broad band source and a scanning fibre F–P (FFP), we demonstrate the above-mentioned operations experimentally.

We propose a hybrid optical bistable device based on a fibre Bragg grating. The experimental set-up is designed by using real communication components. The optical bistable characteristics are simulated. The feedback nonlinearity and the delay time of the device are emphasized. We discuss the potential of such a device in sensor applications.

Photoelectric Hybrid Optical Bistable Device Using Fibre Bragg Gratings with Two Feed Signals

Hongan Ye, Xinming Zhang, Yong Zhu

A photoelectric hybrid optical bistable device (OBD) is investigated by using fibre Bragg gratings as a light-intensity modulator. A new operation with two feed signals is proposed, and with this method the output characteristic of the OBD is remarkably improved. The potential application of such a device in optic stabilizer for fibre laser is also briefly discussed.

Optical switching method based on two diffraction gratings bistable system

Piotr A. Kisała, Sławomir Cięszczyk

This paper presents properties of all-optical bistable fibre switch using two fibre Bragg gratings and rare earth elements doped optical fiber. It is not possible to obtain bistable properties at low switching power level in case of a single fibre grating. In this article the method of optical switching that uses all-optical switch has been proposed. It has been achieved by varying the refractive index of nonlinear optical material as a result of light signal amplitude changes. Presented optical bistable device can be used both in contemporary optically switched networks as well as in optoelectronic sensors, owing to their high achievable resolution.
