Micromanufacturing of Geometrically and Dimensionally Precise Molecular Single‐Crystal Photonic Microresonators via Focused Ion Beam Milling

Abstract

Highly reproducible manufacturing of organic optical crystals with well-defined geometry and dimension is important to realize industrially relevant all-organic microelectronic and nanophotonic components and photonic integrated circuits. Here, programmed shape and size alteration of square-shaped perylene crystal resonators into circular disk and rectangular geometries is demonstrated using the focused-ion-beam milling technique. The fabricated smaller sized circular disk and rectangular crystal resonators display shape- and size-dependent optical modes. Due to generality and high reproducibility, this processing technique can be also extended to other organic crystals to create optical components suitable for commercial nanophotonic device applications.
