Abstract: Systems and methods for controlling environmental illumination relative to circadian function of individuals are provided. A method is provided for controlling the operation of light sources by assigning a circadian state to the individual based on received electronic information, extrapolating future circadian states based on the assigned circadian state, the assigned circadian state or the extrapolated future circadian states including at least a biological night state, and encoding machine-level control commands that control the operation of the light source for transmission to the light sources adapted for the biological night state by having circadian-significant attenuation along the circadian active wavelength range.

Abstract: The optical device provides dispersion adjustment or compensation using resonant coupling between a first waveguide and a second waveguide which has a variable thickness and a significantly different index of refraction. The two waveguides are optically coupled about a lateral coupling surface, and as light propagates down the waveguide, it passes from one waveguide to the other at a predetermined position along the propagation axis depending on the thickness of the second waveguide. Mode converters are used at the input and output of the device to provide for more efficient operation. The first waveguide can be made of silica and the second waveguide of silicon, thus providing a differential in the index of refraction of about 2. For dispersion compensation, in which shorter wavelengths need to be retarded with respect to longer wavelengths, the profile of the thickness of the second waveguide is such that shorter wavelengths spend more time in the silicon than do longer wavelengths.

Abstract: The antiresonant waveguide apparatus is for periodically selecting a first series of at least one optical wavelength from a first incoming light signal. It comprises a first waveguide having an input for receiving the incoming light signal, the first waveguide having guiding mirrors for guiding the incoming light signal, one of the guiding mirrors being a first partial reflectivity mirror; a second waveguide having guiding mirrors for guiding an outputting light signal containing the first series of at least one wavelength; and a first Fabry-Perot resonator adjacent to the first partial reflectivity mirror, and forming one of the guiding mirrors of the second waveguide. The Fabry-Perot resonator is a second partial reflectivity mirror for the second waveguide. The Fabry-Perot resonator has a predetermined thickness determining the first series of at least one optical wavelength transmitted through the Fabry-Perot resonator from the first waveguide to the second waveguide.
