The disadvantage of this method is that designers may not be able to check the performance of the whole system.

LENS STUDIO 3.2 HOW TO

Alternatively, reference shows how to design metalens for a given phase profile using Lumerical FDTD software. The example system shown in Figure 1 can be found in attached “phase profile example.zar”. The macro to generate the blaze grating can be found in our Knowledgebase article How to calculate the sag of a diffractive optical element with a macro. It also discusses the fabrication with single-point diamond turning machine. Reference shows an example of generating blaze grating from given phase profile. The required design and fabrication methods can be very different depending on the types of microstructures. This chart does not cover the details of the design, for example, the microstructure can be traditional blaze grating or modern metalens. Figure 1 shows a flow chart for the process.

Then the microstructure is designed based on the given phase profile. In this process, users first design the required phase profile for DOE/metalens with ray-tracing method.

1.1 Phase profile -> microstructure -> experimental verification Reference and examples are provided if available. In this section, some well-known design processes are briefly discussed.

LENS STUDIO 3.2 UPDATE

If users provide new information or have any requests, please feel free to reach out to us and we can update this article accordingly. Since the simulation technology develops fast, it is possible this article does not cover all the methods available. In the last section, some useful DLLs customized for special phase profile design are introduced. More details are discussed later for concept of phase profile and propagation methods in free space and DOE/metalens. In this article we start with a brief introduction of some possible design routes. Many design processes require two different optical theory/algorithms to separately handle the beam propagation in free space and in microstructure, while others use only pure ray-tracing to achieve the goal. Designers need to decide the strategy for their systems case by case. There is no generalized method to handle all situations. Simulating and designing for systems including DOE/metalens are always tricky. The main goal is to provide designers, new to this topic, a starting point to see what methods are available in OpticStudio. In this article, design processes for diffractive optical element (DOE) and metalens are discussed. Some useful DLLs to support special DOE or metalens design method are also provided in attachment. The concept of phase profile and local grating is discussed. In this article, we briefly introduced design processes for diffractive optical element (DOE) and metalens using OpticStudio.
