Abstract
The present invention relates to a device for controlling optical frequency (F, F) about a central working frequency (F). This device comprises a vertical cavity () formed of two parallel and partially reflecting walls (,), and a membrane () comprising at least one layer (,) structured in the form of a photonic crystal. In this device, the two walls (,) are separated by an optical distance substantially proportional to half the wavelength (λ) corresponding to the central working frequency (F). The membrane () is integrated between the walls (,) of the cavity () and devised in such a way as to exhibit a mode of optical resonance at this central working wavelength (λ). At least one layer of the device is made up of at least one portion of a material exhibiting nonlinear optical properties. The present invention also relates to various systems implementing means of optical pumping and such a device for controlling optical frequency, as well as to a method of manufacturing such a device for controlling optical frequency.
