TopOpt as an inverse design tool was first developed in the context of solid mechanics in the late 1980s. Finally, we demonstrate the superiority of using gradient-based TopOpt compared to a genetic algorithm (GA) when solving a photonic design problem (Section 6). Then, a number of possible extensions are discussed, and code-snippets for easy implementation are provided along with design examples (Section 5).

The MATLAB code is then explained in detail (Section 3), followed by two application examples providing the reader with targets for reproduction (Section 4). We briefly detail the model of the physics, followed by the discretized TopOpt design problem (Section 2). The code is written for scientists and students with a basic knowledge of programming, numerical modeling, and photonics who desire to start using inverse design in their research. This paper details a 200 line MATLAB code, which demonstrates how density-based topology optimization (TopOpt) can be applied to photonics design.

Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity".Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump.Example: (diode OR solid-state) AND laser.Note the Boolean sign must be in upper-case. Separate search groups with parentheses and Booleans.Keep it simple - don't use too many different parameters.
