Abstract

The optical bistabilities of ZnSe and ZnS interference filters have been studied since 1977 when Karpushko and Sinitsyn reported the first experimental results. We see from papers published that (a) it is appropriate to study and compute optical bistabilities of interference filters by a Fabry-Perot resonator; (b) during the fabrication of bistable optical devices (BOD) the parameters such as incident angles, transmission power, and influence of peak position error on BOD, etc. were not studied in detail; (c) the authors could not resolve the problems of transmission peak height for large absorption materials such as ZnSe. We propose a new method of designing BODs of interference filters to study these problems precisely.

Calculation and design for bistable optical devices of nonlinear interference filters

DeGui Sun, Na-Xin Wang, Zhao-Heng Weng +2 more

Three mathematical models for calculating and designing bistable optical devices (BODs) of nonlinear interference filters are compared and the necessity of using the accuracy matrix model based on the principle of thin-film optics to study optical bistabilities of nonlinear interference filters is confirmed. The relationships of important parameters, such as δl'0, δlt, and δl0 with the initial detuning δ, which are very helpful in designing the BODs, are calculated and plotted. The dispersive relations of ZnSe thin-film are introduced into the method to make the theoretical method self-consistent. Finally, experimental results of a BOD of nonlinear interference filter whose construction is calculated using this method are given.

Dynamic nonlinear properties of dielectric interference filters

We report the use of the nonlinear optical responses of multilayer dielectric interference filters to investigate the electron dynamics of thin-film ZnSe. Filters with spacer layers of ZnSe deposited by both vacuum thermal and molecular-beam techniques are investigated. Using cw irradiation from a 30-mW He-Ne laser, nonlinear Fabry-Perot action and optical bistability are observed for a number of filter designs.1

A Critical Phenomenon-Based Optical Bistability in Vanadium Dioxide

R. S. Rana, David D. Nolte, F. A. Chudnovskiǐ

The characteristics of nonlinear thin film etalons and interference filters are being studied because of their potential use as optical logical elements1. Low-power optical bistability in thin film nonlinear interference filters has been demonstrated at room temperature using zinc sulphide (ZnS) and zinc selenide2 (ZnSe). These bistable devices rely on electronic nonlinearities to operate. A switching power of 5 mW and switching speeds of 1 ms - 10 μs are typical for these devices.

OPTICAL BISTABILITY IN MOLECULAR BEAM DEPOSITED ZnSe/BaF2 MULTILAYER INTERFERENCE FILTERS

Alan Miller, Ian T. Muirhead, K. L. Lewis +2 more

Complete interference filters have been fabricated using ultrahigh vacuum molecular beam techniques and optically assessed. The wavelength dependence of optical bistability is compared with theory between 676 and 521nm for a 6 µm thick filter with ZnSe/BaF2 multilayer reflectors. Both dispersive bistability and bistability due to increasing absorption were observed at 514nm.

Complete ZnSe interference filters exhibiting optical bistability have been fabricated using ultrahigh-vacuum molecular-beam techniques. The wavelength dependence of the critical switching power was measured at five wavelengths between 521 and 676 nm for a filter with two-period ZnSe/BaF2 multilayer reflectors and an initial assessment has been made of their long-term operational stability.
