Abstract

A novel optical bistability device is proposed and analysed in which the Stark effect of a multiple quantum well is used in combination with a negative resistance device. The device is found to possess an excellent on/off ratio (19:1) and high speed capability (τ<10 ps), while the required optical power P is as small as 1 mW or less with a bias voltage of 5 V, giving a Pτ product of 1˜10 fj.

A novel optical bistable multiple-quantum-well phase modulator

The authors present a new type of optically bistable phase modulator utilizing a self electrooptic effect device (SEED) integrated with an electrooptic wavelength modulator. An electrically bistable SEED, operating on the principle of the quantum-confined Stark effect, controls the bias voltage across an electrooptic waveguide phase modulator to produce optical bistability. A control signal at 0.848 mu m, corresponding to the first electron to heavy hole exciton transition in GaAs/AlGaAs multiple-quantum-well is used to switch 1.152 mu m light propagating through a waveguide in a direction normal to the control beam.>

Model of optical bistability in the quantum-well self-electro-optic-effect device

John C. Englund, Chi C. Sung, Y. Q. Li

Optical bistability of the multiple-quantum-well self-electro-optic-effect device is studied using a detailed model for a P–I–N photodiode under a constant voltage bias. By solving the Maxwell equations with the experimentally determined absorption function, bistability curves are obtained as functions of the incident frequency and of the bias potential. These results show good agreement with previously reported experimental data.

High-Contrast Multiple Quantum-Well Optical Bistable Device with Integrated Bragg Reflectors

Monolithic bistable microcavities with a GaAs/Al0.3Ga0.7As multiple quantum well active layer and AlAs/Al0.1Ga0.9As Bragg reflectors have been fabricated by metalorganic vapor phase epitaxy. The design of the whole structure is such that a good cavity finesse and a high contrast in the reflective mode are simultaneously obtained. This results in a bistability power threshold of less than 3 mW at 838 nm and a contrast ratio as high as 30:1. A new method is proposed, which allows to measure the nonlinear refractive index in a quasi-continuous regime, and in the operating conditions for bistability. The nonlinear index is shown to saturate at higher power, which evidences the need of a good cavity finesse for such bistable devices. Memory effect is then demonstrated: the sample can stay in either of its two stable states for more than 1 ms without spontaneously switching, and for input pulses as short as 60 ns. Finally we describe two-beam experiments with a new experimental configuration, also in reflection, which allows to mix the two input beams and extract the output beam with an ideal 100% efficiency.

InGaAs-InAlAs multiple quantum well optical bistable devices using the resonant tunneling effect

Yuichi Kawamura, Hiromitsu Asai, Shinji Matsuo +1 more

New types of InGaAs-InAlAs multiple quantum well (MQW) optical bistable devices using the resonant tunneling effect are investigated. The bistability of these devices is obtained by the negative differential resistance (NDR) of the MQW resonant tunneling diodes (RTDs). Two types of MQW bistable devices are described. One is an MQW optical bistable device consisting of an MQW-RTD and an MQW modulator. Light-output-light-input bistable operation is obtained for this device at room temperature. The other is an InGaAs-InAlAs MQW resonant tunneling phototransistor (MQW-RPT), which shows a clear bistability in the collector-current-light-input characteristic. Inverter-type optical bistable operation with an on/off ratio of more than 10 dB is obtained by using the MQW-RPT as a laser driver. Optical memory operation is also demonstrated.>
