Further guidance for broadband antireflection coating design.
Recent investigations have added to and refined the understanding of the behavior of broadband antireflection coating designs and provided further guidance for achieving more nearly optimal designs. The ability to optimize designs wherein the overall optical thickness of the design is constrained to a specific value has allowed this investigation. A broader bandwidth than previously reported ha...
متن کاملExpanded viewpoint for broadband antireflection coating designs.
Examining spectral regions outside of the band where an antireflection coating is specified can aid in finding optimal design solutions. The reflectance versus wavenumber plots at low frequencies indicate the overall thickness of the design. These plots also point to whether the design will provide the minimum possible average reflectance in the specified band. It has been discovered that these...
متن کاملBroadband Antireflection Coating Design Performance Estimation
The application of a few basic principles, some empirical data, and experience is applied to estimate the average residual reflection expected in an AR coating as a function of bandwidth, wavelength, overall thickness, substrate index, available coating materials, and number of layers. This can be a useful tool for not only the thin film designer but also the non-designer or system engineer to ...
متن کاملColloidal subwavelength nanostructures for antireflection optical coatings.
A two-dimensional (2D) subwavelength nanostructure for antireflection coating is fabricated upon a transparent substrate. Self-assembled 2D colloidal crystals are used as a nanoscale composite material with controlled thickness and low refractive index. The feature size of the structure is approximately 105 nm. The structure is used for antireflection coating, and the measured reflectivity of a...
متن کاملDynamic etching of silicon for broadband antireflection applications
An electrochemical etching technique has been developed that provides continuous control over the porosity of a porous silicon layer as a function of etching depth. Thin films with engineered porosity gradients, and thus a controllable gradient in the index of refraction, have been used to demonstrate broadband antireflection properties on silicon wafer and solar cell substrates. A simulation w...
